There are so many songs that make me feel like I've ascended out of my body, particularly Basso Profundo Orthodox chants...Maybe that's a bit too niche lol, but "We Bow Down Before Your Cross" is incredible and makes me feel like I'm floating.

As for more conventional songs, Bestrafe Mich by Rammstein gets me grooving every single time. No matter how many other songs I discover and love, this one remains my favourite. Tied with that one is TOOL's Wings For Marie - It gives me incredible chills, and was perhaps the first song I ever heard that I felt truly changed me as a person somehow.
