Title states it all. My game is only slightly modified and consists mostly of the Vanilla Expanded mods. I also have P-Music, which I consider to be a critically necessary mod, but I don't think it's a mod conflict because it's never happened before in 1.0.
Maybe u/TynanSylvester should look into their being no raid music in vanilla.
That's odd, I've been hearing it on streams as usual.
