Dude I'm pretty much level 6, but mostly electronic.
I'm trying to expand my horizons, but my heart is set on electronic music, mainly EDM/IDM. If it's electronic and has good mixing/melody and doesn't sound generic, I'll probably like it.
I'd say electronic wise, furthest I've gone down the "levels" would be no-fi, Aphex Twin, and vaporwave.
Electronic music means more to me than life. And I really, really love life.
But I also love rock if it has a good meaning. Mainly System of a Down and Avenged Sevenfold.
