"Boom Boom Pow" is a hit single by the Black Eyed Peas released as the lead single from their upcoming album The E.N.D.. The song uses the auto-tune vocal effect, and blends the genres of dance pop, electro-hop and hip hop.

"Boom Boom Pow" has remained the #1 single on the Billboard Hot 100 and Pop 100 for seven consecutive weeks, the group's first U.S. #1. It has also topped the Canadian and UK singles charts and reached the top ten on over ten other charts worldwide.

The single was a huge commercial success, selling 465,000 downloads in the U.S. in its first week of digital release, the third-largest number of download sales in a single week in history, and the largest single-week and debut-download totals by a group in the history of digital-download sales tracking. Thanks to very strong digital downloads and massive radio airplay in the following weeks, the song has become the group's first U.S. #1, topping the U.S. Billboard Hot 100 and Pop 100 for seven consecutive weeks. The song is the second single ever to sell one million first month download sales, after Flo Rida's Right Round.[3][4] "Boom Boom Pow" has also been a huge international success reaching the top ten in multiple countries and #1 in Canada, the UK, and elsewhere.
