I think the song you heard before the NC game with Florida was "Gator Hunting" by Cool Ray. They play all of his latest songs on a local Columbus radio station. "Knock Em Off" is his new one about the USC game (a coworker heard it on his way in to work today, so we looked it up, and ironically I saw this thread shortly after I found the songs so I figured I'd share). There are a few you can stream on his myspace page, and it looks like you can buy the rest for $0.99.

I don't know the guy, nor am I trying to spam or sell anything, so mods feel free to delete this if it's over the line.
