NMIXX ‘Birthday Wish’: Why Fans Question a Chart That Changes Overnight

Fans celebrated a No. 5 peak. Days later, a discussion asked how to interpret a chart that changes hour by hour. Is following the numbers becoming more stressful than enjoying the song?

NMIXX released the album Strange Muse and ‘Birthday Wish’ on October 19. Reporting from that release confirms a No. 34 debut at 7 p.m. and a No. 5 peak at midnight October 20. The October 28 9 a.m. Melon TOP100 page lists the song at No. 52.

On October 24, a Reddit fan alleged daytime positions in the 30s and overnight falls near 85, but those historical hourly values were not independently verified. Melon’s 2021 TOP100 announcement used equal weights for 24-hour and one-hour usage by day and only 24-hour usage from 1 to 7 a.m. Any subsequent policy changes need current confirmation.

Four perspectives appeared in the comments: (1) concern about mainstream reach; (2) a sense that viral success is unpredictable and competition is intense; (3) a choice to stop tracking hourly ranks and enjoy the music; and (4) continued music-show support while acknowledging fans cannot control public tastes. None is presented as a universal fan view.

Changes to the time window and weighting can move a rank, but a single ranking cannot tell us listeners’ identities or motives. Historical chart methodology and any later amendments should also be kept distinct.

Independently established ranks are No. 34 on October 19, No. 5 at midnight October 20 and No. 52 at 9 a.m. October 28. The 30s-to-85 swing is an unverified user observation. Melon’s historical 50:50 formula concerns 24-hour versus one-hour usage—not streams versus unique listeners. No chart manipulation claims are established.

The meaningful next test is how rankings and listener responses develop over days, not one hourly high. A current official methodology confirmation remains desirable.
