WTAE has an exhaustive list of fan songs for the upcoming Super Bowl. I say exhaustive because I was exhausted from listening to garbage. I've compiled what I thought to be the best of the lot. (Which means that they are.) The people making these songs clearly love pop music, but with the base turned high enough even those songs are tolerable.
And of course:
If I missed any you personally feel are the best, let me know and I'll add them immediately.
