Editor: iTunes CD Barcode is a small application that allows you to scan the barcode of a CD and have iTunes play the tracks of the CD stored in the iTunes library.
I have all my CDs imported into iTunes, but the CD cases/covers are still around. When guests or I myself want to listen to a CD while browsing the CD cases, they just have to hold the barcode to the scanner and the music starts to play.
Since there is no central Internet database of CD barcodes, so you need to assign the barcodes to your music first before you can use it. The program has a Learn and a Search mode.
