Yeah, you end up with some of the following labels: Ambient, Art Rock, Avant-Garde, Chill Out, Downtempo, Electro, Electronica, Experimental, Instrumental, Minimal, Minimalism, New Age, Orchestral, Soundscape, Synth-Pop or Symphonic. All before adding any perceived style like fusion, progressive, trip hop, etc.!
The definitions for my own music collection are still being finalized, but I'm starting with four primary categories:
- Classical Music
- Easy Listening & Holiday (mostly inherited from my parents)
- Electronic (I don't use the term "Electronica" so this is where anything electronic or Psytrance goes)
- Music (for all music that doesn't fall into one of the other three main categories)
Someday I should probably add genres, subgenres and styles to the Classical Music category (like "Baroque," "String Quartet," "Requiem" or "Piano") and, quite frankly, I really don't care for most of the stuff in the Easy Listening & Holiday category but, for the other two categories, I use about two dozen primary "genres" for each. Then, all the extra, weird subgenres and styles (like death metal, shoegazing, math rock, psy breaks, etc.) get put into a subgenre field that I can search later to make playlists from. Note that I consider "Metal," "Progressive" and "Rock" to be primary genres, but "Progressive Metal" or "Progressive Rock" would be subgenres.
I'm sure I'll tighten things up a bit once all my music has been imported (so far over 170,000 songs out of over 300,000 are in), but this is working well for now.
