You'll be forgiven if you have trouble distinguishing "Mayhem" from Asphyxia. They both have a similarly heavy '90s techno-rock sound, they were both used for non-highlight music on NFL Primetime, and they were both composed by David Rogers & Paul Shaw. Even I've occasionally second-guessed which one I was listening to when sifting through Primetime clips. My advice for distinguishing them: Asphyxia was mainly used for Game Balls, while Mayhem was mainly used for Inside the Numbers. To help illustrate, here's the ItN segment from the first week of the 1999 season.
