2006
This song relaunched both Justin Timberlake and Timbland's career. It definitely brought sexy back in a good way. 2006 in my eyes (or ears) was the best year for club hits. Nelly Furatado's relaunch. The Black Eyed Peas, Akon, Young Dro, Ne-Yo, Ludacris, Lil jon, Cassie, Nelly, Yung Joc and Sean Paul. There were club hits for every type of person.
Runner Up:
Nelly Furtado - Promiscuous
The Black Eyed Peas - Pump It
Cassie - Me & U
Yung Joc - It's Goin' Down
Young Dro - Shoulder Lean
Dem Franchize Boyz - Lean wit it, Rock wit it
