That. Is. Not. The. Game. Soundtrack!
There is actually a way to manually record every single in-game track in lossless quality, thanks to a nice little feature (once you "buy" every game track in exchange for in-game currency, you can play them in your greenhouse).
If I had a REALLY good sound cable (not the shitty one) I could just do it myself. But I don’t have one 🙁
