One note: I can't stand rap, so I won't advocate any of it. Now that that's out of the way...
No matter what, you'll need Queen. Definitely "We are the Champions," but "We Will Rock You" and "Another One Bites the Dust" could be useful too.
There's an IRI playlist in this thread:

Hope it helps.
[edit]Just thought of one more... "Keep Fishin'" by Weezer from their "Maladroit" cd. And maybe "Another Postcard" by the Barenaked Ladies, if you can find an MP3 of it somewhere...[/edit]
