5. "Crack Addict" By Limp Bizkit (WrestleMania XIX)
Limp Bizkit are one of the most polarising bands in modern music. Some hate them, their place as champions for nu metal earning their scorn for the depths to which they helped drag rock music early in the 2000s. Others appreciate them for what they were: a fun rock band who never tried to wow critics or win Grammys. Whichever side of the argument one falls on, their contributions to WrestleMania theme music cannot be denied. In 2003, the band supplied its second song to the Showcase of the Immortals. "Crack Addict," described as the latest hit from an upcoming album, became the fight song for the top Superstars on the roster at one of the most star-studded events in WWE history. Feuds pitting Hulk Hogan against Vince McMahon, The Rock against "Stone Cold" Steve Austin and Kurt Angle against Brock Lesnar were accompanied by the song in video package and promo pieces leading into the show. The band even took to the stage to perform the song at the event. "Right now/let's go/me and you/toe-to-toe" may not be classic or terribly inventive lyrics but they fit the proceedings. A wrestling show with so many intensely personal matches, the "f*** you" attitude of it reflecting the sentiments of the performers on the roster. Alas, the song was never released on album. Instead, it was released much later through the band's official MySpace profile, of all things.
