To Mr. Thumbs Down:
I understand why they included Taylor Swift. The NFL is always trying to broaden their fanbase and she's a family-friendly megaselling pop star. Still I could also understand the big thumbs-down for her since she appeals mostly to young girls. But Dave Matthews Band is one of the best bands around today and have been for quite some time. Their musicianship is off the charts and they put on an amazing show.
Plus, they are a band with nationwide appeal who just so happens to LOVE New Orleans. While I'm not a huge fan of their music (I do like some songs), I love seeing them play live because their improvisational skills are so impressive. They will put on a great show for however much time they are allotted to play.
