my personal experience on this.
I genuinely wanted to hear exols out cause whenever I said that "exo wasn't known for their singing", which they aren't, somebody said that they were and basically like I was trippin. So cause I'm fair and it's been forever since I listened to kpop for real. I listened to a compilation of literally every best Exo vocalist in their prime, listened to the opinion of professionals and got a good unbiased view then to compare. Then, I looked up the vocals of your average run of the mill pop star in america to get a view of our standards-- then I watched a Exo's main vocalists best moments video at random, like I just picked something fans gave a lot of views and the comments were good...
I burst out laughing so bad, I had to take a break. I could literally tell that they were stretching their voices way beyond capacity, in their average range of course they are decent but not in any way known for their voices, I even checked periodically to see if a video of great merit was out there. It's about just as good as anyone who calls themself a singer should be. So moral of the story just trust your first mind. American singers who are lazy, have better vocal technique in their sleep, but I suppose compared to those who literally can't sing at all they are god tier in korea, but definitely not all of asia though, and most definitely not enough to be compared with other artists who are known worldwide for their singing that still sticks with me.
I even heard they make the poor trainee's hold their breath and all sorts of weird stuff to make them talented. Apparently they all do it and it's an sm thing. To me it doesn't really help much, they also train them in a sort of opera style to help project their voices but that doesn't mean you can go higher, you have to start extremely young and train in a very specific way to properly pull that true opera voice off. They need to leave that to the italians because it's not clicking like that for them. It's extremely nasal and clogged, and I can never hear any true bass in the voices. They leave that to the rappers who can't really go too much higher. Anyway definition of overexposed, fandoms are just cults that demand devout loyalty people truly can't decipher true from fake.
"I stan real singers" *checks video* are you fucking with me
