See the thing is I manage my collection on my work PC, and play it either through my Karma on the move or Squeezeboxes at home. I almost never listen to my music directly at the PC so in a lot of respects iTunes is wasted on me.

When I say manage what I mean is making sure I've got complete tags, checking for typos etc. Still finding typos/duplications years after ripping most of my CDs...
