I don't see it. I would notice becsuse I prefer it Dark Souls style; no music anywhere except where it would really punch things up a notch like the title screen, the hub area and during a boss fight.

Even Elden Ring has normal BGM and it's fucking weird compared to DS and BB.

Could you maybe have turned on a "streamer" mode by mistake? That setting basically turns the music off in a lot of games; especially ones using liscenced tracks.
