Have you noticed recently every group can get a top 10 hit in Korea easily?

Every recent Kpop release chart in top 10 Korea, both girl groups and boy groups. Jisoo, Seventeen BSS, StayC and Txt all peaked at top 2 Melon. Ive and Newjeans just breathes and gets PAKs. Jimin songs always go top 10. NCT Dream got a #1 hit. Upcoming comebacks from Stray Kids, Lsrfm, Aespa, Ateez, Enhypen, Kep1er will probably all go top 5 Melon as well. If we remember just in 2019, only 3 Kpop songs hit top 10 Melon, people said Kpop was dying in Korea, now every group can get them, even boy groups when just last year no boy groups seem to chart well. I wonder what change that suddenly makes Koreans listen to Kpop so much? We used to have top 10 full of ballads this time of the year but now Jisoo, Newjeans, Ive and StayC occupy the top 6.
