OMG is a dance pop song by American singer Usher, taken from his 2010 sixth studio album, Raymond v. Raymond.
The song features American rapper will.i.am, who wrote and produced the song.
It was released on March 22, 2010 as the fourth overall single from the album and was met with mixed reactions from critics, who criticized the use of auto-tune.
That notwithstanding, the single peaked at Number 1 on the US Billboard Hot 100 and Rhythmic chart as well as on the UK R&B and Singles charts.
It also topped charts in Ireland, Australia and New Zealand.
Tidbit: This song was the fifth best-selling song of 2010 in the US, making sales north of 3.8 million units.
