#4 Saliva

Saliva is a very much used band throughout the 2000's in WWE. The band's first exposure with WWE came in late 2001 when their song 'Click Click Boom' was used as the theme music for No Mercy that year. Their song 'Superstar' was next featured as one of the themes for WrestleMania X8, which would also feature a live performance for the band.
The Dudley Boyz also used the song 'Turn The Tables', as their theme for a while, which was written by the band for the sole purpose of being used as their theme.

WWE would later use the bands next biggest hit, 'Always', as the theme for Survivor Series 2002, which included a live performance during the show of the song at WWE's The World restaurant. The band's next biggest hot, 'Ladies and Gentlemen' was used as a theme for WrestleMania 23, while the song 'Hunt You Down' was used for No Way Out 2009. Saliva's song 'Don't Question My Heart' would be used as the theme music of WWE's ECW brand from 2008 - 2010.
