|Make your own at MoreCowbell.dj
Here's a great application for you music lovers. Visit the site at the link above, upload an MP3 from your computer, and then improve it by adding more cowbell. I think Mick Jagger really benefits from that treatment, and I'm experimenting now with an improved version of ABBA's Dancing Queen to surprise my wife.
Go ahead, you can really explore the studio space.
