My pop made a great point about the piped-in music - "when you have bajillions of TV timeouts you have to have enough music to play." I might care more for the music if it wasn't cliche stadium music (AC/DC, Journey, Guns 'N Roses, Sweet Caroline - surprised they didn't play Enter Sandman), but I do wonder if the all-out control of the networks on the game procedure has something to do with it.
Maybe the networks want loud music when they come back from commercial? But I think it mostly is the obsession with a "marketable" product, like the game is not enough to please the crowd, and doing it like everyone else does.
I haven't seen anyone bring up the timeouts; the second half in particular had tons of really long TV timeouts that ruined the flow of an already-dragging ballgame.
Where I went to grad school, they remodeled the basketball arena, and starting running ads and piped-in music during timeouts instead of the band. The students hated it, but after a couple years everyone who knew the old way graduated and the outcry quieted, and now it's here to stay. Boo.
