Your task is to get the data, and that's what I answered. At some point you have to get the data from the stack of CDs. Taht could be you typing or scanning a lot of barcodes, or sticking the CD in the drive for a couple of seconds. You can make your own judgement about which you want to do, but then, you asked about populating the database, not the end user interface.

I've already done this for myself and a few other people. I let the installed music player look at the CDDB for all the CDs then take the data it stored on all of those CDs for the database. I don't have to write a lot of code that way.

I'm sure there a freeware or shareware program out there that does what you want already, though :)
