iWannaSleep: sleep timer for Mac iTunees

Here's a brief plug for a piece of Mac software I use almost every day. iWannaSleep is a simple app that stops iTunes after a timer runs out. I often go to sleep listening to audiobooks, and I use iWannaSleep to set iTunes to stop playing the audiobook 20 minutes after I go to bed. iWannaSleep can also put your computer to sleep, shut it down, or run a custom AppleScript.
