I've been thinking, we've unfortunately created culture where we're only interested in the new. After a couple years, if that group hasn't had a "hit" we move on and never give them a chance even if their music is good. This trend started noticeably in the 3rd gen, but it was even happening in the 2nd gen. Lots of middle tier girl groups have really strong starts, a comeback which is also moderately successful, then they fall off the face of the earth in terms of relevancy and there's nothing they can do to release a hit.
These are all groups who have experienced this phenomenon. Had they gotten a first win with their debut, they'd probably be at least WJSN's level of popularity today. So close to reaching success, but because they barely missed it, now nobody cares. Perhaps thats why so many people are discussing "this group is the new nation's leader" when they just debuted because this is their crucial time to make it or the only time they really care because "look new group, I stanned since day 1" It makes me think about how people say Pristin would be a top tier group if they didn't disband. Tbh I think they would have suffered a similar fate because it would have been too late to make it and people would have moved on.
I also think about, what if (G)i-dle didn't debut when they did. They literally had perfect timing for their debut to get a first win fast. Had there been lots of competition, they might have be at CLC's level of popularity today. IVE is another one who had really lucky timing and a really good song. Now they're destined to be a top tier group, but if their debut wasn't so strong, they'd struggle.
I also think about how Purple Kiss and Weeekly are kinda experiencing this right now. Billlie is in an okay position right now, this next comeback will be crucial. Lightsum and Tri.be better comeback soon because it's gonna be too late. Secret Number has also fallen fast in terms of popularity.
Sure there are a few exceptions, but not many. Fromis9 was able to grow gradually but they were lucky they got acquired by Pledis/Hybe and that took them to the next level; they got that push they needed. A group could go viral after promoting for years like Brave Girls or Momoland, but that popularity usually doesn't last. Dream Catcher has been able to steadily grow I guess but they've been popular internationally since debut so they essentially "made it" overseas even if they didn't in Korea. Same with Loona.
Just random thoughts. This was kinda longer than I was expecting. I just wish if an older group released a genuinely good song, we gave it a chance. That never happens which is too bad.
