As a Murican who has spent every Philadelphia Eagles football home game tailgating for over 20 years now , I can say the parking lot tailgate is pretty much broken up into 3 groups.
Late 40's and up plays Classic/Hard Rock AC/DC, Zepplin, Metallica, Guns N Roses
Early 30's - Late 40's Mostly 90's rap and Grunge- Alice in Chains, Soundgarden, Tool, Wu Tang, Notorious BIG, Mobb Deep
Under 30's - Mostly Lil Pump and Post Malone with a few Meek Mill songs in.
All of these songs are playing at the same time as loud as the car speakers can get , or Ion tailgaters can get with random people screaming Go Birds, or doing the Eagles chant every 5 minutes or so.
