For real, it's about the only thing that reliably causes ego dissolution and bliss for me. And I've spent decades with various meditation practices. Nothing beats music.
They are often songs that are attached to important emotional events in my life, sure, but there are also songs that come out of nowhere and still give me goosebumps. Some things are just that moving!
If goosebumps are only "mildly to moderately pleasurable", I really need to know what kind of music the author listens to!
