This is a strange one. A site that adds cowbells and Christopher Walken samples to any mp3 uploaded. I'll give it a whirl!!!!

I tried it three times and it says, "I am sorry, I don't know that song." :'(
I am trying again now...
funny. I bet the guy who created this site has every MP3 he ever wanted in his colection now. clever.
