MAC Week 2-1 DB Quickies: CD Ownership, Music Sharing or Spontaneous Listening

I love music! As I walk through my day there is a beat in my head, remnants of a drive into work. My collection is broad from George Straight to Metallica and every old house techno to Jars of Clay. Ninety percent of my collection is on CD. I purchased my first MP3 player four years ago. I never download music until my MAC. Very cautious of what could happen. iTunes is great, expensive but worth it.
