WrestleMania is the event where WWE superstars are born and immortalised so it was no surprise that WWE recruited Saliva to both provide their hit single "Superstar" as the theme song of the 2002 broadcast and also perform it on the show. The band kicked off the event, injecting the show with some nu metal energy right out of the gate. The song played over the official highlight package, a vastly superior song to Drowning Pool's "Tear Away", the night's other theme. Unlike the more methodical Drowning Pool track that failed to energise the crowd as the band took to the stage later in the show, Saliva's hit was energetic and heavy. Their performance at the top of the broadcast brought an energy to the show that would define the event. Saliva would provide the company with countless other pay-per-view theme songs, as their brand of music fit the Ruthless Aggression era image of the company.
