I would have to say Eminem that would be pretty cool! Other wise no-one because im not really a big fan of collision soarse althoiugh it has got my cousin and her friends to like Linkin Park which is cool. Then she started liking Live in Texas! So she likes Linkin Park really so collision coarse was good for gettin new fans. But with another rapper i feel the music doesnt have as much feeling into it although it sounds good!
the coup, jurassic 5, or kanye west (imagine mike and kanye in the same studio 2gether - lots of creativity to go around)
