Timbaland's spotty sideline career as a rap artist kicked off in 1997 with "Up Jumps Da Boogie." Tim turns in a capable performance, as does Missy, but Magoo, Tim's partner in rhyme at the time, torpedoes the song with faceplant bars like "I come cause I'm a nut" and "You tight like virgin pussy." It's borderline cringe-worthy, but Aaliyah periodically comes in and tidies things up with a soulful chorus.
