Grown Kids was an American electronic/pop music project active in the mid-2010s, blending EDM-driven beats with melodic pop hooks. The group had a short-lived presence but gained attention through collaborations with notable vocalists from different genres, showcasing a modern, cross-genre approach to production.

Grown Kids collaborated with Taka on the track "Bottle Rocket", released on August 16, 2014. The song also featured Megan Joy, merging electronic pop textures with Taka's emotionally charged vocals. This collaboration marked a unique moment in Taka's career, highlighting his versatility outside of ONE OK ROCK's rock-driven sound.
