Fixing the five-tap detour between a driver and their playlist

Fixing the five-tap detour between a driver and their playlist

Four studies with 165 people showed the trouble came from how Apple Music is organized. We redesigned the path to a playlist, and it tested well. One spot kept coming back in every round: the Now Playing screen.

The Outcome

The Outcome

What we found, and what we told Apple to do

What we found, and what we told Apple to do

Three findings came out of the research, and they turned into five recommendations in priority order. Everything below this section is the evidence behind them.

Finding 01

People couldn’t guess where playlists live

Apple’s menu groups music by type, and playlists don’t fit how people think about their music. When we stripped the screens down to plain menu labels, people who went looking for Apple’s curated playlists split four different ways.

Research backing: 21 of 53 people never found Apple’s curated playlists, and only about a third went straight to them. When 27 people sorted the music themselves, 18 made just two piles: music they saved, and music picked for them.

Finding 02

Asking people if it was easy would have hidden the problem

Nearly everyone said the menu made sense, including most of the people who had just failed to find what we asked for.

Research backing: of the 21 people who couldn’t find curated playlists, 17 still rated the test easy and 18 said the labels matched what they expected.

Finding 03

Every method pointed back to Now Playing

Our walkthrough flagged it before we tested anyone. In the first round, people couldn’t tell which playlist was playing. After the redesign, getting to Now Playing was still the hardest task and the most common complaint.

Research backing: 5 of 6 people in the first round couldn’t confirm what was playing. In the second round, about 1 in 4 of 79 people brought up Now Playing on their own.

Recommendations delivered

HIGH

Keep Now Playing on every screen

Show a Now Playing bar on every screen, including inside a playlist, that says what’s playing and opens it with one tap anywhere on the bar.

It was the hardest of the three tasks for 79 people: the most “difficult” ratings, the lowest label match, and the most written complaints. The bar we tested only appeared on two screens.

HIGH

Show the playlist name on Now Playing

Add “Playing from: [playlist name]” under the song title.

5 of 6 people couldn’t confirm which playlist was on, and 3 wrote in asking for exactly this. We designed it but never tested it.

HIGH

Ship the redesigned path to a playlist

Put recent playlists on the home screen with a play button on each one.

77 of 79 people called starting a playlist “very easy,” and all 79 said the labels matched what they expected.

NEXT

Retest finding Apple’s curated playlists

It was the task that failed hardest in the tree test, and we never went back to test it on the redesign.

NEXT

Test it in a car

Every session ran on a laptop or phone, so we never measured real driving distraction.

People kept raising it themselves. One summed up our prototype as “made for the passenger.”

Why CarPlay was worth evaluating

Why CarPlay was worth evaluating

CarPlay puts your iPhone on the car’s built-in screen and ships in 98% of new cars sold in the United States. Apple Music comes preinstalled on every one of those phones.

That is about as strong a starting position as a product can have, and drivers still open Spotify instead. When we looked at why, it came down to effort. Reaching a playlist in Apple Music takes 4 to 5 taps. Spotify takes 2 or 3. Apple’s own Phone app does its main job in 1. In a car, every extra tap is another moment looking at a screen instead of the road, so the extra effort costs Apple listeners and puts drivers at risk at the same time.

Apple’s own Phone app already does its main job in one tap. We weren’t asking Apple Music to invent something new, just to catch up with Apple.

How We Got There

How We Got There

Research methods & findings

Research methods & findings

Six methods over one quarter. We started with our own expert review, then brought in real CarPlay users to test the problem, and tested again after the redesign.

Expert review · defining the problem

Cognitive walkthrough

Before involving anyone else, we walked the five steps to playing a playlist ourselves, as a first-time commuter would. At each step we asked four questions: will they try the right thing, will they notice the button, will they understand it, and will they know it worked? We judged 6 issues across 20 checkpoints, 3 of them serious, all in the first three steps. Playing music worked fine. Getting to it didn’t. One of those issues was the one that started this project: the controls to open and play a playlist were small and sat on the far right, away from the driver.

Competitive analysis · 7 products

Three music apps competing for the same drive (Spotify, Amazon Music, YouTube Music), two carmakers’ built-in systems that skip CarPlay entirely (Tesla, Toyota), and two apps that set the bar inside CarPlay (Apple’s Phone app, Audible).

User research · testing the problem, then the fix

Open card sort · 27 people

We handed people eight kinds of music content and asked them to group it however made sense to them. Artists and Albums ended up together 89% of the time. Playlists landed with Songs only 57% of the time, and 18 of 27 people sorted everything into just two piles.

Tree test · 53 people

A plain-text copy of Apple Music’s CarPlay menu with no visuals, so any trouble had to come from the structure itself. Seven tasks were written as goals (“you want to browse Apple-curated playlists”) without naming where to go.

Qualitative usability test · 6 people

CarPlay users clicked through a copy of the original design while talking out loud (a think-aloud test), so we heard where and why they hesitated instead of asking them afterward.

Quantitative usability test · 79 people

A larger group ran three tasks on our final prototype, each followed by two questions: how hard was that, and did the labels match what you expected? This told us how many people struggled, where round one told us why.

Six of seven tasks landed between 75% and 100%. The seventh dropped to 60%, and it was also the slowest. People didn’t agree on where to start: New first for 41%, Home for 23%, Library and Search for 14% each.

47 of 53 people said the labels matched what they expected. Of the 21 who never found curated playlists, 18 said the same.

47 of 53 people said the labels matched what they expected. Of the 21 who never found curated playlists, 18 said the same.

That gap is why we measured what people did and didn’t stop at asking them how it went. A satisfaction survey on its own would have called this menu fine.

The Redesign

The Redesign

Three design decisions

Three design decisions

We kept CarPlay’s look and changed its structure, so your playlists show up the moment the app opens. The original took 5 taps from the CarPlay home screen to a playing playlist. Our goal was 2.

01

Put recent playlists on the home screen, ready to play

Your recently played playlists sit at the top of the first screen, each with its own play button, so starting one takes a single tap.

Research backing: 41 of 53 people in our tree test said saved playlists are what they mostly play in the car, and Apple’s own Phone app already does its main job in one tap.

02

Split your music from Apple’s picks

Home, New, and Radio hold what Apple suggests. A tab called My Music holds what you saved, with Playlists and Artists one tap away.

Research backing: 18 of 27 people sorted music into those same two piles on their own, and in the first round of testing, 2 of 6 stumbled on the word “Library” and suggested “My Music” or “Saved” instead.

03

Bigger buttons, clearer cards

Larger tap targets, and a small icon on each card showing whether it’s your playlist, a radio station, or live audio.

Research backing: our walkthrough found the playlist controls small and far from the driver, Apple’s own Phone app uses larger targets built for the car, and 1 of 6 people couldn’t tell playlists from albums or audiobooks.

What held up, what didn’t, and what we left open

What held up, what didn’t, and what we left open

We tested with real users twice: first on the original design to find where people got stuck, then on our final design to see if the fixes worked.

Round one: 6 people, original design

What people ran into What we changed
5 of 6 couldn’t confirm which playlist was playing Designed a tag on Now Playing that names the playlist
2 of 6 tripped on the word “Library” Renamed it My Music
1 of 6 couldn’t tell playlists from albums or audiobooks Added a small icon to each card

“If I really want to know the playlist, obviously you have to click a lot… so then that’s probably not so safe.”

Starting a playlist: 77 of 79 called it very easy, and every single person said the labels matched
Getting to a playlist: 71% called it very easy, and 91% said the labels matched

Still weak

Getting to Now Playing drew the most “difficult” ratings: 10 people, against 2 and 0 for the other tasks
Only 75% said its label matched what they expected

Why Now Playing kept slipping

Our final design had a bar at the bottom showing the current song, but only on the home and My Music screens, and it read “Resume Playing,” which sounds paused. Inside a playlist, where the task started, the bar disappeared. The only way to Now Playing from there was a small icon in the corner, or pressing Play.

Home · the bar is there

Inside a playlist · no bar

Same prototype, two screens. The bar people were looking for wasn’t on the one where the task began.

“I expected there to be a bar on the screen where I can see the music that’s currently playing.”

Round two participant

Our walkthrough had actually flagged this a month earlier. Our early sketch already added a clearer Now Playing icon and label, but the walkthrough couldn’t score it because Now Playing wasn’t one of the five steps we walked. It took real people to show us how much it mattered.

What we’d do differently

Measure what people do, not just how it felt: round two collected ratings, and the tool marked Task 3 done as soon as someone pressed Play. Next time we’d record whether each task was actually completed and how many taps it took.
Check the task wording against the screen: Task 3 said “You’re viewing a playlist. Go to the Now Playing screen,” but nothing was playing yet. A quick pilot would have caught that.
Close the loop on what we fixed: we never retested finding Apple’s curated playlists, the task that failed hardest, and we never tested the playlist tag we designed after round one.
Test it in a car: every session ran on a laptop or phone. How long someone looks away from the road is the thing that matters most here, and we couldn’t measure it sitting at a desk.
