Keep getting "stop playing on another device" popup even though I'm not playing music on any other device.

I just sub Apple Music, and I am facing this problem. Every single song keeps on popping up stop playing on another devices...

I don't have any other devices!

Gosh, I'm thinking of a refund and switch back to Spotify.

I keep getting this message on my MacBook Air though I'm not playing on my phone, and I'm not trying to play any music on my Mac. Apple Music is idle in the background. It happens when the Mac wakes up from sleep. I might even get a bunch of these messages at the same time. And I was not playing any music when the Mac went to sleep. The Music app was on paus in the background.

What works for me:

• disconnect all airplay devices from the music app (HomePod, in my case)
• restart the music app
• play music
• reconnect airplay devices

Somehow, the music app gets confused when in starts while airplay devices are connected. It's a nuisance, but I'm trying to remind myself to disconnect while I'm not playing music all the time.

I managed to fix this by resetting my entire Apple Music.

macOS

1. Setting.
2. Click your Apple Account.
3. Click Media & Purchases.
4. Click Manage... on Account.
5. Login.
6. Under the Account Setting, scroll all the way down where you see Reset.
7. Warning, this will wipe all the downloaded songs, clean out uploaded songs.

I found out the matched songs are the cause of the problem; now I manually re-add songs from Apple Music cloud. None of them are giving me anymore problems.

Might be worth checking if you have a pending airplay connection on another mobile device. Just a guess, but Apple might have a problem automatically disconnecting / detaching devices since the HomePod appears to cut the Apple cloud connection short.

Nope, simply in the app make sure audio output is only on the local device, not remotely connected to any AirPlay speaker. Than restart the app. That’s all.
