I've listened to Kpop for 7 years and it's actually rather boring to me now. I'll still give things a listen but most of my favorite groups don't put out stuff that interest me anymore.
Bands I still somewhat pay attention to are SHINee (though their recent album was blah), Infinite (no good releases for a long time but I still love the members), VIXX (they're a relatively new group so they haven't grown too stale yet), and SNSD (their latest single without Jessica wasn't that great imo).
I feel so critical lmao I guess I'm just disappointed that a fandom I used to be so into doesn't leave me excited anymore.
