Omen is the nineteenth single released by The Prodigy. It was released on 16 February 2009, and it is the first commercial single from the album Invaders Must Die. The release was officially announced on 9 January, in a newsletter sent to fans and it was first played on BBC Radio 1 on 12 January.
The single was co-produced by Does It Offend You, Yeah? singer James Rushent and features a remix from the Dutch drum and bass group NOISIA. The track was The Prodigy's tenth top ten hit on the UK Singles Chart.
The song won the Best Single award at the 2009 Kerrang! Awards. It came in at #68 in the 2009 Triple J Hottest 100: the fifth track by The Prodigy to chart in the annual countdown, following "Voodoo People" in 1994, "Breathe" and "Firestarter" in 1996, and "Funky Shit" in 1997. The song itself is featured in the movie Kick-Ass and also on the soundtrack respectively.
'Omen' is called 'O' in Germany? That's because there is a german dance act from the 90's called Magic Affair. They filed a suit against The Prodigy because they had a "hit" single called 'Omen' back then. Anyway this has nothing to do with sampling them or anything. It was just all about the title of a song.
