NMIXX has achieved a significant milestone by ranking 35th on Mediabase's Top 40 Radio Chart for two consecutive weeks. Initially entering the chart at number 38 during the week of January 25 to January 31, 2026, they have now ascended three spots to secure the 35th position. This accomplishment underscores NMIXX's growing global presence. The group achieved this feat with their title track 'Blue Valentine' from their debut studio album 'Blue Valentine,' released on October 13, 2025. The song topped major domestic music charts, including Melon's Top 100, daily, and weekly charts, and maintained the top spot on the monthly chart in November 2025. Additionally, NMIXX is set to make history as the first K-pop group to perform at the Viña del Mar Festival on February 24, 2026.
