Madonna hooked up with two of hip-hop's top beatmakers —
Timbaland and Pharrell Williams — for her eleventh studio
album. "She just wanted energy, she just wants to dance," says
Williams, who produced about half the disc, including "Beat Goes
On," featuring Kanye West ("It has a Megadeth-dance feel," says
Williams), and the raw, synthy house jam "Give It 2 Me." Justin
Timberlake co-wrote and co-produced several tracks, including the
Timbaland-produced single "4 Minutes." "She was like, 'I don't want
any ballads, I just want people to move,'" Williams adds. "It's
like a sex and workout album."
