The answer is "Satisfaction" by Benny Benassi. Known for its racy video featuring scantily clad females using powertools, "Satisfaction" along with the Boogie Pimps' "Somebody to Love" helped bring the genre of "tech" up from the underground.
In addition to remixing everyone from Outkast to Goldfrapp, Benny also produced the crossover smash "Tu Es Fouto (You Promised Me)" by In-Grid. For more information on Benny Benassi, check out the interview.
