ASMR is more of an immediate thing. Sound -> reaction. Generally whispers trigger a lot of people. Binaural/panning sound is another one. One of my favorite ASMRtists do this "ksksksksksks" sound that triggers it. Haircuts are what caused most people to realize they have it, and there's actually a "virtual haircut" video (that I linked to in another comment) that triggers almost everyone. Bob Ross is also known for triggers, but I personally don't get triggered by his videos. As I said, music can be a trigger, it's just generally not. There's specific sounds that would trigger. But if it's just buildup/atmosphere, that's not ASMR as far as I'm aware. For me it's a pure sensory thing. Most people would agree that "asmr" caused by music is frisson, not asmr. I've never experienced anything similar to ASMR at all while listening to music, with the exception of a few songs that literally have asmr triggers in them.
