If you think about it, the only "true" HipHop songs that would work with the existing Rock Band format would be some of the old school cuts like "Walk This Way" - Run DMC ft. Aerosmith, The Message, Wild Thing, etc. Most current HipHop songs are too repetitive (as well as horn, keyboard & sample heavy), and would only work if a turntable and/or keyboard component were introduced to the current list of available instruments. (Making it HipHop Band, or Rap Star.)
The only kind of rap I can actually tolerate is in songs like 'Livin' on the Corner of...whatever' by MC Frontalot. That song isn't bad. The drum chart's awesome.
The Beatles | Coheed and Cambria | Dream Theater | Megadeth | Metallica | Symphony X
Run-DMC is the only rap group I'd want. Raising Hell for DLC?
I will not remove this until Badmotorfinger is offered as full-album DLC.
"You're an angel witch, yoooou're an angel witch."

here is a Better suggestion for you
Please Vote for Muse
Do want to see some rap, not any of the new crap that's out there. Gotta see some good stuff, also has to have real instruments, not that electronic crap. That kinda makes it tough, but I think it could be cool.
