Can rap find a place in music games?

We understand why Stephen Totilo at MTV's Multiplayer blog is concerned about the lack of rap music in rhythm games like Guitar Hero and Rock Band. He noticed that when playing drums on "Sabotage" (the closest thing that Rock Band has to rap) he was bored by the lack of structural changes in the song. Totilo says that he's not the first to realize this: Even Harmonix chief Alex Rigopulos has said that some big changes would need to made to the Rock Band formula to accommodate rapping.

But we would submit that both need to do some outside-the-rock thinking. There are lots of rap tracks that we think could be fun. We present the above video as Exhibit A. If your tastes run a bit more Old School, we've got another after the break. What would your picks be?
