tl,dr: `systemctl suspend`

Sometimes I let my pc play music at night. Spotify still didn’t manage to implement a sleep function (even gorram Audible has this – and chances are the app crashes way before anyway).

I usually use `shutdown -h 60` or similar. Suspend tho? That’s another story. Hint: “suspend” is a bash builtin and not what you’d expect 😉

Looks like this changed (again) from `pm-suspend` to
 systemd:

> sleep 1h; systemctl suspend

No sudo. yw.
