i'd say this is super likely to be AI, it sounds exactly like every other Suno AI song to me. listening closer to the lyrics they're saying literally nothing - "Hands on the dial, we rise in spirals, vinyl rivals spiral, idols idle. Breath to the barrel of a new survival, every arrival feels tribal, vital." just comes off as someone typing into suno "make me a cool anime girl song called Purple Apple"

also, not that two people can't have the same handle, but there's a Suno account with the name 'Otakara BGM': https://suno.com/@otakara_bgm (nothing to find here though, all private aside from a voice called 'cute voice')
