Boom Boom Pow was released in 2009 by the Black Eyed Peas as the lead single from their album The E.N.D. Written as a futuristic club track for the digital age, it topped the Billboard Hot 100 for 12 weeks and became one of the defining pop hits of that year. Its stark beat, vocoder effects and chant like hook made it easy to sample, remix and cut into short clips. It remains popular online because that opening energy is instantly recognisable, even to listeners who never hear the full song.
