The track contains a sample of Afrika Bambaataa & Soulsonic Force's 1983 song "Looking for the Perfect Beat".
The vocals interpolate Grandmaster Flash & Melle Mel's 1983 song "White Lines (Don't Don't Do It)" and Afrika Bambaataa & Soulsonic Force's 1982 song "Planet Rock".
It was released as the album's lead single in February 2006 and remained on the U.S. Billboard Hot 100 chart for three weeks, peaking at number eighty-nine.
The song debuted at number two on the Billboard Hot Digital Songs chart and made a strong Hot 100 re-entry at number four.
The track broke a record previously held by Jay-Z's 1998 song "Hard Knock Life (Ghetto Anthem)", which had re-entered the chart in March 1999 at number twenty.
