I SUCK AT MUSIC TRIVIA

A friend who shall remain nameless is coming to town next week and offered to bring me songs and DVDs from her secret "mostly-legal I'm sure" stash. So far I have drawn a blank. Then it hit me. I need Outkast. So here is my lame ass email in its entirety:

Maybe bring me some of that Outkast music (I already have Hey
Ya). And I know there are some other black guys who have cute songs that
40-year-old suburban-misfit mommies listen to, but I just don't know their names.
It's those songs credited to "blah blah featuring someone else."

Help me.
Please.
