Before Google Play Music was shut down in lieu of YouTube Music, it had a feature that a lot of people found useful. It was a timer that you could use to stop music playback at a specified time. It was the sleep timer, and it was useful if you knew you were going to be away from your phone or if you were going to be asleep. This way, the music wouldn’t play all day or all night. This was great for people who were using their cellular data.
YouTube Music could bring sleep timer
With any luck, this feature might actually make its way over to YouTube Music. The folks at 9To5Google (via Android Police) were able to find a string in the latest version of the YouTube Music app that points to this feature.
Since this was an APK dive, you’ll want to take this information with a grain of salt. This could happen, but there’s still a chance that Google will take this feature out of the app in the future.
