Other genres stump me pretty bad though. Psychedelic rock and jazz to name two big ones. Both aren't catchy or contain lyrics making it notable less emotionally powerful I think, especially since unlike classical they generally aren't composed to express emotion. So I think it comes down to a basic appreciation of aesthetics for some genres.
Jazz is about the soul. It is emotional but thru a different direction to the way rock does. Their instruments sound more "lyrical". It has to do with aesthetics too.
Psychedelic rock is about trippyness. Like Dream/Space Rock, it also goes for the mesmerizing sounds. Trippy harmonies. It is also emotional man. Pretty much all melodic music is emotional.
Is it really that worthless to value human skill and aesthetics over someone else's emotions though? I mean I think there is a time and place for most any music.
First, that's a complex question, separate human skill from aesthetics.
If the prime reason you listen to such music is mostly based and FUCK THAT GUY IS GOOD, then yeah you're pretty much missing the whole deal.
Now, if you say, I love this music, and then it turns out the guys are really fantastic technically, that's fine!
The argument that arises here is that musical talent and dig the music are cause and effect, it is an intertwined thing, etc. That's bullshit.
I dig Victor Wooten's album A Show Of Hands, because the album is fantastic. Then I am told bass and voice are the only instruments there and I say FUCK ME!!
But then I listen to What did he say, his second album I think, and don't dig it as much. BUT THE GUY HAS TREMENDOUS TALENT JESUS CHRIST.
You see? it is a matter of knowing how you set your priorities.
