Perfect for playing files off the iPod in conjunction with iPodDisk:

iTunes doesn't let you access your iPod's music if you sync your music to your library, which in my case is on external drives. Much less hassle to use this app when away from home. It even has out of the box Growl support and global shortcuts! Very nice.
