I was suffering from this yesterday, I noted the following behaviour.
After/While running the music the screen still detects input even with it off
After the music had closed music-app was still in powerd [0] and I could interact with any app with the display off
Only a restart of the device resolved the issue.
0 - $ powerd-cli list
powerd-cli: Running as user is not fully supported.
