Fade your iTunes music out while you and your Mac fall asleep
Nov 14, 2010 - 1 Comment

Sleepytime is a simple app that functions as a sleep timer for iTunes and your Mac. You set a time for iTunes to stop playing and then set a fade interval, and your Mac will stop playing iTunes gradually, before finally sleeping your Mac.
It’s a free download (donationware), you can download Sleepytime from here.
