I listen to new music by composers who are interesting to me. I listen to some; I don't know if I want to call it pop, but it's some interesting artist that gets my attention, I listen to in the mornings.
You have to train your mind and your ears, but they're more like athletic skills. So, part of music you just have to learn those things or you can't practice the art.
Works of art should be stimulating. They should wake people up rather than acting like a sedative.
