Music rhythm games have taken the videogame world by storm. From Dance Dance Revolution to Guitar Hero and Rock Band, there's something for just about everyone.

Scratch is all about urban hip-hop music and infusing your creativity into the game with a unique turntable peripheral. To learn more about the game, IGN went to Dan Lehrich, creator of Scratch: The Ultimate DJ.
