It certainly doesn't hold a candle to the CBS College Football Theme, but I don't think it's terrible. Just not catchy.
Also, refusing to call it the "SEC on CBS theme" is a hill I will die on. It long predates the SEC deal, and it wasn't league exclusive. I watched way more CUSA, MWC, and Army-Navy games with that theme than I ever did with the SEC, and that will continue with the B1G.
