As I said, some of the music is just the audio of a video, but they also get a lot of releases directly from the publishers. They are both on YT Music and the difference in quality in between them is noticeable.

I have my audio quality set to high in that options menu btw.

For GTA SA I remember chittychittybangbang to make your car fly.

Youtube Music doesn’t just serve the audio from a video. They do serve the audio from a video if nothing else is available, but they also get releases directly from the publishers/distributors.

The difference in sound quality is definetly noticeable.
