The Metallica third down song is irrelevant, because everybody is doing the guitar strum and chanting 'F* Penn State'. For the entire south endzone crowd, that music is about as ingrained as the band's 'First Down, Touchdown' and 'RU Rah Rah' songs.
Playing Don't Stop Believing stopped being cool around 5 years ago when I was still a student, so no it doesn't elicit universal enjoyment from the crowd.
The song played for the team's entrance has always been chosen by them, so that's irrelevant to this conversation of fan enjoyment.
Barring the points I've already made, you're using a grand total of FOUR songs (out of at least 25 played, including tracks by Calvin Harris, Avicii, Kendrick Lamar, among many others) and to try and implore which music myself and fellow students/young alumni enjoy most. You're welcome to continue sitting in the upper deck and making false observations.
