After getting Brittney Spears on his last single and an all-star group of artists on the remix, will.i.am is back with a new track. The song, titled "#thatPOWER," happens to feature Justin Bieber on the hook, with will.i.am dropping two verses over the dubstep-influenced beat. The song happened to come out on the occasion of will.i.am's birthday, which is today.

"#thatPOWER" will appear on will's upcoming album, #willpower. The album is slated to be released on April 9.
