So, what I don't like about this game is... it depends on both a companion app and a Spotify or Apple Music subscription? It doesn't even contain the music you have to hear?
I guess it's a cheap way of doing a game (so you don't need to license the music), but that game will stop working soon as some API changes and the companion app is updated, or as licensing in some songs change and stop working in the game.
But I guess that, now you have the URL, you could make an Open Source app that mimics the Hitster app, and even download a package with all the songs on MP3 to have offline. Don't know it that was @wuemeli idea...
