Saturday Night Live's "More Cowbell" sketch, featuring Christopher Walken as mega-producer and cowbell aficionado Bruce Dickinson, brought us some of the most-quoted lines of the decade.

Now you can automatically add them to any mp3, along with -- what else? -- more cowbell. MoreCowbell.dj makes the whole process easy, and it sounds better than you might expect.

Upload a track, adjust the cowbell slider and the Walken slider to your liking, and hit the "Gimme more cowbell!" button. Your cowbell-ized track will be delivered in embeddable form, so you don't have to worry about hosting when you want to share it. You can just send a link.

There's also a "recent cowbells" page, where you can listen to other people's ideas of songs that needed more cowbell. The site does a good job of analyzing songs to keep the cowbell on beat and insert the quotes during rests.
