Have played it at a few parties, because it's an ass-kicking song. Have no issue with it being played at RU games on occasion, but don't think it should be a "feature" song that gets played most/all of the time.
As others have said, those should be songs unique to RU or NJ in some way and as @e5fdny said, that means songs like Don't Stop Believin' or big songs from NJ artists like Bruce or Bon Jovi or even Sinatra. And if we're going to play a fairly cheesy old songs that were big hits back in the day, why would we choose Sweet Caroline, which has been used by so many other teams and use Brandy, by Looking Glass, a song that was just as huge (it was #1 in 1972) and was done by a band that formed at RU?
Unfortunately, with regard to more recent NJ/RU/NB acts, the pickings are a bit slimmer. Sure Bouncing Souls from NB has "Ole" which has been used at sporting events before, but not as much recently and it was never a "hit" that would get everyone singing (probably, unless they played it enough). And Gaslight Anthem is from NJ and got their start at RU basement shows, but while they were pretty big, they weren't HUGE.
So, if we wanted to pick a song that is ginormous (was #1 for 12 friggin' weeks), fairly recent (2016), would be a huge singalong favorite and features a bona fide Jersey girl, look no further than "Closer" by the Chainsmokers, featuring Halsey. It's one of my favorite pop/EDM hits and would absolutely get the crowd singing, as I would think almost everyone knows this song (featuring one of the hottest videos ever). If Mr. Brightside can be a sing-along at football games, certainly this could. Might not be upbeat enough for football, although Sweet Caroline ain't exactly a hard rocker either.
