More exploration done and can safely say that Astral Fields track doesn’t work in game.
Muted everything in game except music and went to Astral Fields and Bysmiel questline area, the one with Galfang.
Re entered those locations for 10 times to be sure, but sadly I could never hear the music playing. I thought the music could actually play, but be very quiet, so I maxed the volmue to the levels of heavy metal concert, but still no music. (speaking of loud music, Krieg boss theme is way louder than the rest of the game, even the phase change and ending track. Just compare how loud the Steward boss music plays and what earrape you get after his death)
For Dreeg’s area, I had a good man on Discord who tested it and he also couldn’t hear the music, so I am not the only one who cannot hear the track playing.
In conclusion, Astral Fields and Korvan Memories/Remnants/Sorrow don’t play in game even when they were supposed to.
