Released in 1989 as a single from Mötley Crüe's Dr. Feelgood album, Kickstart My Heart was written by bassist Nikki Sixx and became one of the band's signature anthems. Its relentless tempo and biker-rock attitude made it a stadium and sports-arena staple through the 1990s and 2000s, while placements in films, games and commercials kept it in front of new audiences. Online, the isolated opening circulates as an edited hype cue, valued because listeners recognise the riff within seconds.
