Pitchfork: So Lil Wayne is on the Raditude track “Can’t Stop Partying”. How did that come about?

Rivers Cuomo: It might be my favorite track on the album. It was an epic process coming up with it between me, [co-writer] Jermaine Dupri, and [producer] Polow Da Don— and then Lil Wayne topped it off with this rap from the edge of the grave.

Pitchfork: Were you actually in the studio with Wayne?

RC: No, I’ve never met him. I’d love to…He sounds like he’s totally insane— and not just for the sake of sounding crazy. He’s not trying to sound ghetto or gangsta or intellectual— he’s just very natural and weird.

The first time I really became aware of him was when he worked the Ninja Turtles into the song “Kush”. Let me look up the lyrics online. … Ok, he says, “I feel like I’m racing a bunch of little turtles/ Keep a bandana like the Ninja Turtles.” First of all, he rhymes “turtles” with “turtles,” which is crazy! Second, he pronounces “turtles” with this real hard “R” so he sounds super nerdy, which is something you don’t often hear from black rappers. Third, he references the Ninja Turtles! That’s another thing you don’t often hear.
