Damn, you're making me work hard today. I like those ok. I thought I'd go on wikipedia and try and figure out what specific genre's I like, and that is frickin' hard. There are so many kinds of electronic music it's not even funny. And I like a handful of them.
It makes it even tougher that I don't like all of an artist's material. For example, I like some of the Chemical Brother's tracks, but I certainly don't like all of it. Same for Prodigy. I know I rattled off two of the more commericially viable artists out there, but that's because they are accessible to me.
Here is characteristics that I like...I like a strong beat, but not necessarily with a pounding bass drum every other beat. I like songs that can take a hook (if you will), and constantly evolve it, much like a classical Mozart piece. I like some music with intelligence, which is probably some of the reason I like electronic music.
Dubstep certainly fits a few of those, and I certainly appreciate the artistry of it, but it doesn't fit with me as well as some other things I've listened to.
I'm going through my fuze to see what tracks I like, I download a lot of stuff and then never pay attention to what it is that I like.
