Sleep timer?

[Forest Dane]

How long has there been a sleep timer in the drop down menu?
More to the point why did no one tell me?

why did no one tell me?

Sorry, I thought you knew.
I won't make the same mistake next time.

It appears that it's an app I've had a few years now. Never had a shortcut there though before.
I can never understand why sleep timer is so well hidden in play music.
