You gave three examples. I don't think anyone - or next to nobody at least - is arguing for all piped in music to be removed. There are some bangers that clearly the vast majority enjoy. But a good balance would be nice and banishing the band to halftime only isn't balance and would result in even more lame canned content being programmed to fill the void.To me all you have to do is look at crowd/sideline reaction.
How does the crowd/sideline react to the band playing?
How does the crowd/sideline react to Juicy Wiggle, Mr. Brightside, Swag Surfing?
It's no contest really. The band is nice for halftime entertainment but lets leave it to the pumped in music to fuel the in game entertainment.
The louder the better!!!
People complain about not having traditions but then we actively advocate for destroying every tradition we do have.
