NMIXX, a girl group from Australia-raised vocalist Lily and singer Haewon, has expressed their excitement after Billboard named their song "Blue Valentine" the No. 1 K-pop song of 2025 and their parent album "Second Best" of the year. Despite this, Lily emphasised the importance of their fans' reactions and thoughts on their album. The group has also collaborated with Brazil's drag icon Pabllo Vittar on "TIC TIC" and contributed a single for Anderson.Paak’s K-Pops! film soundtrack. NMIXX's current world tour is called Episode 1: Zero Frontier, a title that functions as a statement of arrival and promise of more to come. The band's new EP, Heavy Serenade, is set to be released next month.
