Not OP but I don’t really care if it was or not. All I know is that I’ve been using the Spotify app 10+ years and it works well. I don’t know if this random app works, and if it hasn’t been supervised I doubt it does.

Gave it a quick try today, it works pretty well and is noticeably faster than the official app.

The official Spotify app has some skin in the game. Random dudes self promotion project, not so much.

I suspect the official app would actually be more consistent and not as bad to use if it was generated by an LLM.
