HYBE Labels released a "TNT" mood sampler on its official YouTube channel to preview an upcoming project from the boy group CORTIS [1].

The release marks a critical step in the group's early momentum as they transition from their debut phase to their second major musical offering. As a new act under the BIGHIT Labels umbrella, CORTIS is utilizing these high-production visual samplers to establish a distinct aesthetic identity before the full album drops [1, 2].

The "TNT" mood sampler serves as a promotional tool for the group's second EP, which is titled GREENGREEN [1, 2]. This audio-visual preview is designed to give listeners a glimpse of the sonic direction and thematic elements of the new record. The sampler was scheduled for release on May 4, 2026, at 6 p.m. KST, which corresponds to 5 a.m. ET [1].

CORTIS previously entered the music scene with their debut EP, "COLOR OUTSIDE THE LINES," which was released on Sept. 8, 2025 [2]. The transition to the second EP suggests an accelerated release schedule for the group, a common strategy for new K-pop acts looking to capture audience attention quickly within their first year of activity.

By utilizing the HYBE LABELS YouTube channel for the distribution of the "TNT" preview, the agency is leveraging its global reach to ensure maximum visibility for the group [1]. The mood sampler format allows the group to build anticipation through short, atmospheric clips rather than a full music video or single, creating a curated experience for the fanbase before the official launch of GREENGREEN [1].

The "TNT" mood sampler serves as a promotional tool for the group's second EP, which is titled GREENGREEN.

The rapid succession between the debut EP in late 2025 and the second EP in May 2026 indicates that HYBE is aggressively positioning CORTIS to establish a foothold in the competitive boy group market. The use of 'mood samplers' reflects a broader industry trend where visual branding and atmospheric teasers are prioritized to generate viral engagement on social platforms before the actual music is released.
