Let's get real: we need a band. But we need a band because it's tradition and part of college football and adds to the atmosphere for the crowd. We don't need a band to annoy the opponents. With that said, putting the band in the best place to be heard throughout the stadium makes the most sense - and that place clearly isn't where the band is at currently.
If Snyder wants them behind the opposing bench because he's a mega micromanager and has the pull to be that micromanager, then fine. They can stay there until he's gone in a year or two or whenever. At that point, they should be put somewhere near the north end zone, projecting towards the rest of the stadium. The northeast corner seems like a good option. This is makes good financial sense as well.
