According to multiple streaming data i found:
EASY:
Melon - #4 / (#1 peak)
Circle - #4 / (#1 peak)
Itunes/Apple Musoc - #1 / (#1 peak)
Spotify - #8 / (#3 peak)
Youtube Music - #3 (#1 peak)
I didnt include the other sites like Bugs, Genie etc. since they only hold minor market share compared to Melon. As you can see, they never left the top charts and their daily unique listeners are currently at 15.9 mil monthly unique listeners.. I didnt include their other song "Smart" yet since it just started the promotion but its currently at:
Smart:
Melon - #9
Circle - #15
Itunes/Apple Music - #3
Spotify - #10
Youtube Music - #5
As for Perfect Night, it never left top 20 spots since Nov last year and it always re enter top 10 every week...
For March Brand Reputation Ranking, Lesserafim currently at #2 for group while Kazuha is #3 for member ranking, just behind SNSD Taeyeon and BP Jennie.. Im lazy to research intensively for the album charts for EASY but from i've seen on various media sites, EASY album topped Itunes Album Chart at #1 but CMIIW.. This is their current status only in korea though, in their 2nd market Japan they are currently the uncontested #1 4th gen GG there, and second most popular KPOP GG after TWICE... They earned like $14.6mil USD in Japan alone in 2023, making them the first female group in 20 years to achieve those numbers.. Thats basically in the entire kpop history in japan since KARA,SNSD, TWICE, IZONE and other 4th gen like IVE, NewJeans didnt earn that much..
As for New Jeans, they haven't had a comeback since July.. Their highest charting song right now is Supershy at #29 Spotify and Hype Boy at #30 Melon.. With how fast the KPOP is right now, its easy to lose the public attention to a group who is not very active, especially after 8 months of not releasing any music.. Of course New Jeans is slightly ahead in terms of overall position among the 4th gen BUT when they make a comeback at April/May, IVE will also make a cb while Lesserafim is uncontested during Feb/March not to mention the upcoming Coachella that will either make or break the group as the success there will massively boost their popularity in latin american circle (antifragile,SMART, Fire in the belly)...
The problem with New Jeans is that they didnt made an official comeback last year since they already released GODS, but it didnt do well as expected. It peaked at #10 and then just fell off after Worlds and now they are stuck since HYBE dont want to overlap Lesserafim and New Jeans comeback... Timing is the problem but since they're popular last year, they got some leeway..
