Listening to music + slumber

[johan_vm]

Hi,

I just bought an Android Phone: an HTC Hero.

It's my first smartphone, but I do own an iPod touch.

I'd like the Hero to behave like my iPod:

I like listening to music before going to sleep.
Is it possible to tell the HTC Hero that it should play music for a certain amount of time (eg 20 minutes), after which it should slumber/go to sleep?

With the iPod, it's possible to set a timer (eg 20 minutes)
+ an action that should be performed afterwards (eg slumber iPod)...

I hope someone can help me out...

regards,

Johan
