Lullaby start after some time

Idea is to set time after which lullaby go on.

I do breathing techniques in bed before sleeping​and some time fall asleep without turning Sleep as Android on, I can’t do my exercise with lullaby playing as it destruct me. That would help thx.

Or maybe starting tracking itself (with lullaby) after some time.
