Actually i would say lsf did fine. I wouldn't call fearless a hit song on kcharts but it did decently. Spent 5-6 weeks top10 on Melon. Has 200M+ gaon points and get to 300M which would be mid level. It was never getting better than this with garam situation getting worse with time during their promotions.
Fearless spent 30-32 days inside Spotify global. 17 weeks inside billboard global excl 200 charts. Two bsides above 20M streams on Spotify which is good for a gg album. 400k album sales.
Yeah their stats are not out of the world like newjeans and ive but it's not shabby.
