10. Gnarls Barkley's Going On

2006's "Crazy" was so convincingly insane that most people were disappointed with this reasonable-seeming follow-up. "Going On" is just a sweet soul song about moving past a relationship without bitterness ("May my love lift you up to the place you belong/ But I'm going on"). Still, it's hardly dull. Danger Mouse fills the track with little quarks and shooting stars that rotate deferentially around Cee-Lo's interplanetary vocals. If that's not weird enough for you, at least they made a strange video.
