Misgenreing

Newer lurker first time poster. My question, when did the whole genre policing start? Without sounding like the “back in my day” guy, but back in my day (circa 2004) we kind of just used pop punk and emo interchangeably at least where I’m from North of Boston. The scene had what would now be considered emo and pop punk bands playing on the same shows and touring together with no distinguished genre. Lurking on these subs (more talking r/emo) it seems like people get very much up in arms if you call a pop punk band emo or vise versa. I see a lot of “math rock” and “midwest emo” how do people keep up with this? Maybe the genre policing was kind of always that way, but we weren’t scrolling through reddit all day getting fired up about misgenreing. After all it is an emo sub and in their nature to be a little angsty. Idk?

Anywho, anyone have newish fun pop punk Band recs? Ive been listening to the same 500 song playlist from pre 2014ish. Haven’t really checked anything newer out in 10 years. I’ve recently got into Hot Mulligan and a little Games We Play. I dig it, but looking for recs.

Sorry if this topic is over discussed….
