Timbaland

By 2007, Timbaland got dance-flavored pop down to a science: giant, jittery bass lines; loose, snaking melodies; a guest roster that included some of the biggest names in music. Tim's sexy surrogate Justin Timberlake pops up on a few tracks (the best of which is "Give It To Me," where Nelly Furtado stops by for a threesome), but the real shock will come later when the legendary hip-hop producer teams up with Fall Out Boy ("One and Only"), the Hives ("Throw It on Me") and Elton John (the surprisingly decent "2 Man Show").
