I know that snoop dogg did the doors song and celph titled used guns and roses, do you know any other songs with rock beats or just cool underground rap songs. I like jedi mind tricks and groups like that, any ideas?

Im a hiphop producer and I'm trying to sell my beats to companies such as sprite for some of their hip-hop commercials. Or just for any company that needs beats for urban commercials.

My friends are performing a show, and they invited me to help. They couldn't find anyone else so I agreed, the problem is, I'm a horrible dancer. They've agreed to show me the choreography and the steps, and I'm sure I can get those down, but I'm just so stiff and not fluent

Any suggestions on that?
Any any tips with hip-hop?
I need some suggestions/tips, and any information would be helpful.
Thanks!
