I'm gonna go through 'til I can figure out what's missing.
  SOMETHING has to be missing. I've been making up music on the
  piano forever, and have music in my head but really don't know
  the genres. I'm hoping I'll hear something that "clicks" and
  that will make me very happy indeed.
  http://everynoise.com/engenremap.html   == I'm really liking it.
  I always had a good "sense" of genre - like, I could always tell
  "this song reminds me of" some other song.... or I'd be able to
  describe in detail what's special and common about it...
  although I'd lack the category names... and often the names of
  the songs as well tongue emoticon (my brain has a tagging
  problem I think tongue emoticon ) but I was never good at the
  names of styles. Like, if someone says to me, "deep breakcore"
  (to pick a random example), I've never heard of it before, but
  without hearing it, I know more or less what it'll sound like.
  Yet if someone says to me, "What genre is this song?" I go
  blank. == That's what's making me laugh so hard: I listened to
  the examples and was like, "I can see it I can see the
  connection!" and just imagined trying to EXPLAIN how they're
  related to someone who goes, "wtf are you talking about?" ==
  YES! I found the name of a genre I like and I didn't know it had
  a name: [1]http://everynoise.com/engenremap-fullon.html This is
  awesome for me. I always say I can appreciate all genres of
  music and, so far, this is true. I can find something I like in
  each. But of course, some things are more my speed than other
  things for different reasons. "Full On" which I never heard of
  before, I like. I would've called this "hacker music". or "music
  to hack by". ==
