How to make music stop by itself at night

The problem is simple: you want music while you fall asleep, and you don't want it running until the battery dies. The solutions range from clumsy to good, and most people never find the good one because it is buried in a player they don't use.

Option 1: Android's Bedtime mode

Digital Wellbeing → Bedtime mode can turn the screen grey and silence notifications at a set time, but it does not stop media playback. If you rely on it, the music keeps going; it just gets harder to see the screen.

Option 2: a timer that turns the phone off or mutes it

Some "sleep timer" apps set the media volume to zero after N minutes. This works, but the player keeps running, the notification stays, and in the morning you unmute to find the queue ended hours ago. It is a workaround, not a feature.

Option 3: the timer inside the music player

This is the right tool: the player pauses itself. Most players have one somewhere under the three-dot menu. Two things to check:

• Maximum length. Many stop at 60 or 120 minutes. If you fall asleep to a two-hour ambient mix, you want at least 180.
• End-of-track option. A timer that cuts off at exactly 30:00 will usually stop mid-song. Look for "finish the current track" or "stop after this song"; it costs nothing to implement and makes the difference between drifting off and being jolted.

Good defaults for a sleep timer

1. Quick buttons for 15, 30 and 60 minutes — that is what most people pick.
2. A slider for anything in between, up to 180.
3. A checkbox to wait for the song to end.
4. A visible countdown on the player so you can see it is armed.
5. The timer survives screen-off and the app going to the background — it should run in the same service that plays the music, not in the activity that gets killed.

Playlists that help

Make a short "Wind down" playlist of 8 to 10 calm tracks and set the timer to finish after the current song. If the playlist ends before the timer, the player stops naturally; if the timer fires first, it waits for the song to finish. Either way you don't wake up to silence in the middle of a chorus.

How Plaay does it

Plaay's sleep timer is on the player screen, not in a menu: 15, 30 and 60 minute buttons, a slider from 5 to 180 minutes, a "finish the current song first" checkbox and a countdown shown on the button while it is armed. It runs inside the playback service, so it keeps counting with the screen off and the app closed.
