I too loved "Welcome to the Jungle," and it did seem to do a good job of getting our folks pumped. I hope we stick with it. Its probably a good idea to use a song people are somewhat familiar with...as opposed to Saliva, whoever the hell that is. Playing crap songs will not get people pumped up for a game (if you ever feel the need to test that theory out, then watch Daughtry kick off the next RLF telecast...it will suck the life right out of you).
I do agree that "Welcome to Atlanta" needs to be included in some way on gameday.
