I think the first CD I bought was either Hall & Oates, Madonna or Poison. I can't remember. I started getting CD's around the late 80's though. My collection is now over 300 CDs, but I've got all of them stored in a safe place and have everything backed up through iTunes. Most of the time I just get new albums through iTunes, but sometimes I'll still get the CD if it's a group I really like.
Chris Botti, Paul Hardcastle, Sade, Miles Davis, Edele, and most all jazz and classical I'd like to have CD's for.
