Tonight is music night on the Fox animation block. First, there was a Ke$ha song on 'The Simpsons,' and now Kanye West guest stars on 'The Cleveland Show' (Sun., 8:30 PM ET on Fox). West appears on the show as, um, "Kenny West," a new rival for Cleveland Jr. Naturally, their feud can only lead to one thing: a freestyle rap battle!

So it all comes down to a rap battle between "Kenny" and Cleveland Jr., in a scene that's a direct parody of the film '8 Mile.' Kenny West seems to have the upper hand at first. But after a slow start, Cleveland Jr. demonstrates his shockingly dominant rapping skills.
