This iTunes utility turns your Mac into the most fully featured alarm clock you've ever owned. It'll gently put you to sleep then quietly do the same for your computer. When its time to wake up, it'll wake the computer first, and then rouse you from your slumber with whatever music or radio station you choose. You can even use it to seamlessly change from one playlist to another, changing your party's mood at a specific time (a useful tool when its time for your guests to leave.)
