What is the music that is played following commercials on NFL Network's Thurs/Sat Night Games?

If you watch a Thursday or Saturday Night Football game on the NFL Network, after commercial breaks there is a time when a big announcer voice starts listing the sponsors for the game. In the background there is a track that is totally awesome. It starts off chimes sounding like a Christmas Carol (like Silver Bells) and then rocks out. It's not Hell's Bells by AC/DC and it has nothing to do with the NFL Themes on FOX, NBC, or CBS but it's a little like them. I've searched a bunch on the internet for it and come up empty. Anybody got any help?
