The music world has got it's Kevin Bacon of the Six Degrees game. Weezer frontman and sometimes solo artist Rivers Cuomo has, for years, been writing fun, wry, rockin' pop tracks, including on the band's most recent, Rainn Wilson-dubbed album "Raditude." (Hey, there's at least one non-music connection!)

The music universes of Katy Perry, Adam Lambert, Jermaine Dupri, Lil Wayne, Kenny G, Rob Thomas, Sugar Ray, "Yo Gabba Gabba" and, obviously, the fans have all collided with Cuomo's in some way or another, whether he co-wrote songs, sang some backup, covered a track or collaborated in some other way.

In the following pages we list some of his more recent contributions -- and a wish list that includes  a major pre-teen pop star and a Beach Boy.
