ZEROBASEONE – NEVER SAY NEVER (September 1, 2025)
ZB1 is opening the month with a bang, releasing their first full-length album, NEVER SAY NEVER.

YG’s TREASURE is back with their 3rd mini album, LOVE PULSE, and it’s shaping up to be one of their most polished eras yet. Known for their mix of hip-hop swagger, pop sensibilities, and emotional depth, TREASURE’s new release is said to lean into themes of romance and vulnerability. The teasers feature pastel tones and sleek visuals, showing a softer side of the group without losing their performance firepower. Expect catchy hooks, TikTok-worthy choreo, and plenty of vocal standouts from the members.
MONSTA X – THE X (September 1, 2025)
K-pop veterans MONSTA X are delivering their 13th mini album, THE X, proving their staying power in the industry. MONSTA X is known for their intense stage presence and signature hard-hitting sound, and this comeback promises to double down on that identity. Early spoilers point toward EDM-infused anthems, sexy R&B cuts, and rap-heavy performances that MONBEBEs love. With members showing more personal artistry in production and lyrics, this album feels like both a celebration of their legacy and a promise of their future.
NCT WISH – COLOR (September 1, 2025)
SM’s youngest NCT unit, NCT WISH, is back with their 3rd mini album, COLOR. As their name suggests, the concept centers around brightness, youth, and dreams, and this album builds on that foundation. Each track is designed to showcase the different “colors” of the group’s personality and sound — from bubblegum-pop inspired bangers to sentimental mid-tempos. Their visuals lean toward a playful, trendy aesthetic, making them especially appealing to younger fans discovering NCT. With COLOR, NCT WISH is proving they’re more than just the “newest unit” — they’re ready to carve their own niche.
aespa – Rich Man (September 5, 2025)
Aespa never disappoints when it comes to concept-driven storytelling, and their 6th mini album, Rich Man, is no exception. The teasers hint at a bold narrative that ties into their ever-expanding KWANGYA lore, but also explores themes of power, wealth, and identity. Expect futuristic EDM-pop, trap-infused anthems, and ballads with strong harmonies that showcase their vocal growth. Performance-wise, aespa is set to serve their signature sharp, intricate choreography and cinematic MV production. With each release, aespa continues to solidify their spot as concept queens of 4th gen K-pop.
ChaeYoung (TWICE) – LIL FANTASY vol.1 (September 12, 2025)
ONCEs have been waiting for this — TWICE’s ChaeYoung finally makes her solo debut with LIL FANTASY vol.1. Known for her charismatic rap, unique tone, and artsy personality, ChaeYoung is one of TWICE’s most creative members, and her solo work is expected to reflect her individuality. Early concept photos tease a dreamlike, slightly surreal aesthetic, suggesting that she’s going for an art-pop / experimental pop direction rather than a safe idol sound. Fans are excited to see her deliver a mix of hard-hitting rap, smooth R&B, and emotional vocals, showing her full range outside of the group. This is easily one of the most anticipated solos of 2025.
