I started in junior high, when I was in "Stage Band", buying the stuff we played: Basie/Hefti, Maynard, Woody Herman. I did most of my collecting when recordings were cheap ($1 LPs and $2.99 CDs in the early, cut-throat days of the internet) under much broader horizons: trad to free, rock, world, electronic, techno, disco (just kidding). Reached about 10,000 items, then started traveling 24/7/365 for business and haven't seen my collection for 10 years, other than my annual week of vacation when I reload my MP3 players. Presently buy only the irresistible: Mosaics, other limited edition. Still, I know I'll be dead before I get back through it all. The bulk of my buying today is for gifts; music's still my favorite gift. Alternative and more accurate answer: I collect music these days in the form of memories of live performances.
