Hi Paul,
I've been using
Collectorz cd software for some time now, works great! At first the bar scanner was handy as I was loading ~2000 cds but, it's much faster to simply type in the bar code when adding just a few at a time.
Now that most everything is converted to flac using dbpower onto hdd's I don't see much use for it though, everything is neatly sorted by artist/album(s)/songs right on the discs and or Foobar.
