Career
The Rollout: A Multi-Faceted Introduction
THEBLACKLABEL’s strategy for launching ALLDAY PROJECT was a masterclass in modern, narrative-driven marketing, moving beyond the traditional teaser-photo-and-MV-drop formula. The agency executed a “show, don’t tell” approach, aiming to build an emotional connection with the audience by showcasing the members’ personal stories and artistic motivations before asking the public to judge their music.
The campaign began with the official group announcement on June 9, 2025. This was followed by the release of ‘DAY 1’, a 12-minute documentary, on June 13. This documentary was a crucial strategic move. It allowed each member to present their journey in their own words, directly addressing the public’s preconceived notions.
Only after establishing this narrative foundation did the group release its first piece of music. The music video for the title track “FAMOUS” was pre-released on June 16, a full week ahead of the single’s official drop. This transformed the MV release from a simple music preview into an event built on the character investment and curiosity generated by the documentary.
The pre-release music video for “FAMOUS” garnered explosive viewership, surpassing 2.5 million views in just 16 hours and 10 million views in four days. It topped YouTube’s trending charts in Korea and worldwide, and ranked highly on major music platforms in China, the US, and Brazil.
The group’s official debut took place on June 23, 2025, with the release of their debut single album, FAMOUS, which included the double title tracks “FAMOUS” and “WICKED”.
Early Controversies and Incidents
- Nepotism and the “Chaebol Idol” Debate: The most prominent controversy revolves around Annie Moon. Her direct lineage to the families that founded Samsung and currently run Shinsegae has led to widespread “nepo baby” accusations. Some online communities have dismissed her idol career as a “hobby of a chaebol heiress,” questioning her commitment and suggesting her path was paved by wealth rather than merit. While her personal story shared in the ‘DAY 1’ documentary aimed to counter this by highlighting her family’s opposition, the debate remains a dominant part of the discourse surrounding the group.
- Cultural Appropriation and Aesthetic Recycling: Tazman became an immediate focal point for criticism due to his consistent use of braids in promotional photos and videos. This sparked intense online debate about cultural appropriation, with many critics arguing that it was an insensitive and unoriginal adoption of Black cultural aesthetics. This was compounded by a broader critique that the group’s overall “hip-hop wannabe” vibe felt like a recycled concept from older YG Entertainment groups like 1TYM, rather than a fresh take.
- “FAMOUS” Concept Backlash: The lyrical content of their debut title track, “FAMOUS,” drew significant backlash for its perceived arrogance. For a group that had yet to officially release a song, lyrics bragging about their influence and the desire of others to be like them were seen as unearned and tacky by a segment of the audience.
