Andy Prieboy has put a "musical sketchbook" online entitled "Don't Tell That Guy Anything," consisting of six rejected songs that were lying around on his hard drive. Besides being wonderfully eclectic and giving insight into his own songwriting process, they're great songs (and they're cheap!)
The first one I heard (and the one that still resonates the most for me) was "Thunderbird (V-8 Wonder of the Western World)," with a video created by Edwin Vacek here:
In his writeup about the song, Prieboy reveals interesting things about the music (it was an Apple Loops experiment) and the lyrics. I find the subject of passive destruction and unsolvable hypocrisy to be endlessly fascinating, so it's amazing to see somebody combine those things into a series of beautiful and concise words.
