Jin's "Super Tuna" is inspired by Trot

On the occasion of his birthday, Seokjin, who is celebrating his 30th birthday, came online to interact with his fans on VLive. The popular idol surprised them by revealing that he has a small song for them, titled "Super Tuna".

Soon after his statement, the song was released on BTS’ official YouTube channel. “Super Tuna” has been co-produced by South korean singer Kye Byeom Ju, better known as BUMZU, who provided the background vocals and played the synthesizer. PRISMFILTER's Park Gi Tae played the guitar. Anchor at PRISMFILTER MIX LAB took care of the mix and mastering, while Son Yoo Jung of HYBE Studio handled the recording.

The song “Super Tuna” is a reference to Jin’s well known love for fishing. It happens to be a popular trot song. Trot is a genre of Korean music well known for its vocal inflections.

The surprise single was accompanied by album photos, which mimicked the bright designs and dramatic graphics of trot albums from the 60s and 70s. Fans were also treated to a formerly unseen picture of the idol fishing.

That is not all, the BTS singer even shared a cute choreography video for fans to recreate.
