As far as being able to judge whether music has soul or not, my argument goes like this: music is often compared to literature, poetry, and so on, but I don't buy this (though those kind of perceptions can be a part of music appreciation). I conceive of music more like some kind of kinetic sculpture, that's basically physically boning your earholes. boom-chick, boom-chick foursquare music is obviously not do a good job at thrusting its pelvis, so to speak, so I think it's perfectly fair and even objectively correct to call it soulless and sexless. A corrallary here is the popular association of "simple" music with feeling and soul, and "complex" music with coldness and intellect. The most "complicated" music in the world is the traditional tribal drumming of central Africa, where the whole dang tribe is drumming, each their own unique rhythm, and it all locks into this insane shifting overall groove. I defy anyone to stand up in public and call central African tribes cold and intellectual, but that's just what you're doing when you scorn music as "too complex".
