iTunesShut

iTunesShut is a timer for iTunes. It will allow you to choose how many songs you want to listen to before your predetermined action occurs. Your choices are quit iTunes, pause iTunes, Shut Down, Restart, or Sleep your Mac.

iWannaSleep is an app that does a similar function. One thing I like about iTunesShut is it will allow you to gradually decrease the volume of the music. Just choose what you want the final song to be played at and iTunesShut will automatically calculate how much each song needs to decrease.
