Display MoreYes, variety shows, vlives, social media posts, vlogging/behind the scenes content, and other types of fan based media like those. It's kinda hard to show what you have on award shows and music shows when those are performance and dance based. So it's easier to do during a groups personal content to show to fans and potential fans. Not only that, but with the pandemic is hard to even get on one of these shows for a 4th gen group when South Korea doesn't even pay attention to them. Most people think that 4th gen is a dance competition because the most popular boy groups from big companies are "dance focused" (a false narrative). They do not take into consideration that kpop is not just the big4 and ignore smaller company groups. Newer boy groups who not only have amazing dancers, but also some of the best vocalists of the generation are: The Boyz, Treasure, P1harmony, Monsta X, and Ateez.
Stray kids, Ateez, TXT, Enhypen and The Boyz (just to name a few). As I said before, two of these groups have some of the best vocalists of their generation (one even has one of the best vocalist in kpop not just 4th gen and we all know it's Jongho of Ateez) Even if Stray kids, TXT, and Enhypen aren't as vocally strong as the other two, they are definitely not weak. Seungmin alone is a standout vocalist with a good range. Even Han their rapper has the range, technique, and tone of a main vocalist. TXT and Enhypen aren't praised enough for their vocals. They have softer tones but that doesn't affect their stability which it impressive. And we've seen on I-Land that Enhypen are more than capable of improving and getting even better. TXT get better every era they went from bright and energetic Crown to dark and raspy Lo$er=Lover, that's not easy to do. And Taehyun and Hueningkai even talked about learning new techniques and improving their overall vocal tone and it shows.
I don't think 4th gen's goal is to have a Mariah Carey Vs. Whitney Houston face off. It goes it's much deeper than "dancey songs" it's about technique, tone, vocal range, and emotions that go into a good vocalist. Strong vocals don't equal good vocals. Lots of people have strong voices but their technique, tone, vocal range, and ability to portray emotions is way off (not any idols that I can think of I'm just talking people that are interested in singing in general).
And I didn't even mention the bunch of other smaller groups with amazing vocalists but it's already a long message
I don't consider monsta x new generation tho, they debuted same year as gfriend and twice. Kihyun is part of the older batch of main vocals who really impressed me, so far I haven't seen that much in 4th gen, and like you mentioned jongho from ateez, I know he can sing but even as someone who is not an expert I noticed the way he does high notes can be damaging him? The rest of 4th gen guys in Kingdom weren't really stand-outs imo
My point is that while each boygroup may have their one great main vocal (like ateez and oneus, groups I noticed sing well) the rest of members fall short and sometimes they even drag the whole group down, while previous generations had groups like TVXQ, exo or btob, where almost all members are vocalists and even these that didn't have that position, were above capable.
