MP3 Mercury Rev / If You Want Me to Stay [Sly & The Family Stone cover, 1992]
Funk is an essentially goofy genre. It's a big music complete with big hair and giant basslines, oversized clothes and supersized fun. Mercury Rev takes the goofiness that resides at the chewy center of "If You Want Me to Stay" and sprinkles it all over the outside and edges. Delicious.
(And different somehow from a too-easy "ironic" cover of, say, ABBA or Alanis or Whitney.)
