SO-SO, an internationally active DJ, Music Producer, and Human Beatboxer, has produced <Loop Line> as his first-ever J-POP release, featuring singer-songwriter Tani Yuuki.

The central theme of the song is breaking free from the loop of life.

As we repeat the same routines day after day, our thoughts and behaviors gradually become unconsciously fixed. Through this work, SO-SO quietly questions that cycle, using Loop Line - a metaphor for a circular train line - to deliver a message to everyone living in modern society.
The track is an ambitious piece that reconstructs blues-inspired musical elements - rare in today's J-POP scene - through a modern approach. It fuses SO-SO's human beatbox artistry with contemporary production techniques.
In addition to his vocals, Tani Yuuki delivers a rap performance and contributes his own guitar playing. The warmth of the live instrumentation adds depth to the track, resulting in a fresh and daring sound that transcends conventional genre boundaries.

- Is it truly okay to remain as we are?
- Are we afraid of change?
- Do we have the courage to take a step forward by our own will?

Marking a new challenge for SO-SO as a J-POP producer, < Loop Line (feat. Tani Yuuki) > has begun drawing attention for the new sound created through the cross-genre resonance between the two artists. The song aims to encourage listeners who feel a sense of stagnation or confinement, inspiring them to break free from the loops of their lives.
