Check Mac, Palm and Windows Software Updates and Downloads – VersionTracker for software that will allow you to sleep your machine at a certain time - I'd think something should be available.

Other than that, if it's for, say falling asleep to music, you can

a) build an iTunes playlist that will run out after some time, where the 'Book will fall asleep after a while, or

b) press and hold the "Play" button on the Apple Remote just before you go to sleep - that will sleep the computer as well.

Energy Saver will shut down/ sleep the computer either Every Day/ Weekdays / Weekends / Mon / Tue/ Wed /Thurs / Fri at the time you specify.

Do you mean have the macBook at sleep while playing music?!

That's not possible, because the sleep means that the HD is off, as most of the other hardware elements (a part from some core ones which I don't know, but someone more informed can supply that info).
