I would say more than music, I've done a few short pieces with ambient sound and music, and let's not forget the actual "mix". But... I am kinda new to "post audio", perhaps I am missing your meaning, if that makes sense?
Music, soundscape, background, ambient, etc.
I compose, record and produce original music (instrumental, not so much vocal). I also enjoy doing ambient, sound fx, soundscaping. I guess the later are all pretty much the same thing. :)
