Sure, you’ve all probably heard of Weezer. (Just in case you haven’t, the alt-rock kingpins are on the cover of this month’s issue of AP, so go buy that and familiarize yourselves. I’ll wait.) But what many people don’t realize is that in addition to all the smash hits Rivers Cuomo has written for his main band, he has lent a helping hand to dozens of other artists, earning a slew of co-writing credits along the way. Below is a smattering of the numerous co-writes Cuomo has participated in, with dozens more still unreleased. (I don’t know about you, but I’m dying to hear the song he co-wrote for Katy Perry, “Work It.” C’mon, internet gods, upload that to YouTube already!)
