The most interesting thing about this entry is that CM Punk made two different themes iconic, and both were established songs well before he even adopted them. Living Colour's "Cult of Personality", and Killswitch Engage's "This Fire Burns" both served as Punk's theme, the former for just over two and a half years, and the latter for nearly four. In that time, both became beloved, just as Punk's character was before his exit from the WWE in 2014. Cult of Personality probably takes the cake, however, as it signifies Punk's biggest run in wrestling, his giant summer of 2011, which saw him light the wrestling world on fire while winning the WWE title. Later that year, he'd begin a year-plus title reign in which would rank him among the all time-best WWE champions. Punk may be gone from the wrestling world, but you can "never say never" as it pertains to the entertainment business. If he ever chooses to return, it will be a prime example of how and why Punk was able to take two different pre-established theme songs, and make them his own.
