Some of these 4th generation bg's companies seem to have given up on charting and decided to just pursue their own interests, in my opinion. The claim that "bgs need to develop more gp-friendly songs" is essentially false because all of them have already produced gp-friendly music (such as Wave, Crown, andThrill Ride). They seem to have lost interest in girl groups in general (even 3rd gen bgs don't chart as high as their gg peers these days, and the only 4th gen groups outside of the big 4 that chart well are ive,g-idle and stayc, while in 3rd gen there were much more girl groups from various companies like gfriend,mamamoo and oh my girl..wjsn,lovelyz and momoland too if we considering them lmao they have hits). I've come to terms with the fact that these groups will probably never have a hit song with the gp because of their musical approach, and that's alright (realistically I wouldnt expect normal people to vibe with guerrilla or future perfect in a cafe) Even while I can't really comment on other albums from tiny companies, it's not the end of the world because literally all of them has a strong international fan following that supports them, ensuring that they at least have a steady income from record sales and global tours.
they are looking for a long term investment which is fandom. as long as the fandom enjoying the music and will stay in the fandom and keep consuming their product such as album, tour etc.
