A beginning amateur, who invents piano accompaniments to songs than do not exist yet. As a keyboardist/pianist, I'm more interested in listening to accompaniments alone than to arrangements including voice and accompaniment.
piano
none since I'm beginning, I've fiddled with Audacity a bit

none, since I focus mainly on particular songs
I have many, but I prefer focusing on single songs (and sometimes a passage in particular) than on specific artists or groups.
Ambience musics are certainly my favorite ones.
Indeed, I do other things in my life... but that another story.
