"OMG" is a song by American recording artist Usher. The song features will.i.am, who also wrote and produced the song. It uses the auto-tune effect in several lines, as well as Jock Jams-esque sports arena chanting. It was released on March 22, 2010 as the first worldwide single off his sixth studio album, Raymond v. Raymond, and the fourth single overall, following the three US singles "Papers", "Hey Daddy (Daddy's Home)", and "Lil Freak". The song was met with mixed reception from critics, who criticized the use of auto-tune, but commended the song's dance and club vibe.
