creating a music database

To my knowlege, a bar code is just a unique number to identify an item. The store sets up its own database using the item number as the key.
Sony has a media server (in the $2000 range) that includes a 400 (200?) disk player.
You load the player with CDs, connect the system to high-speed internet, press a button and the system automatically loads the digital CD files to the server!
It also retrieves album cover art and song lists (from where I don't know).
They should have some kind of interface that lets you create a spreadsheet-type listing.

Yes, the perfect product is CD Trustee.

Automatically build your own database of song titles, artists, and albums, simply by inserting each CD into your computer. Takes seconds per disc. Catalog LPs and MP3s too!

I use a program, Readerware which allows one to use the unique barcodes on CDs (DVDs and books also) to catalog them in your computer. I use a wireless barcode reader (one of several recommended by Readerware) to upload the CD album titles (the program uses the internet to get all info including album name, title, and album cover art) into my laptop. I just go to the shelves and scan the barcodes (like is done at cash registers) and the scanner sends them to my laptop. If I am out of range of my laptop, then the scanner stores them until get intorange and then uploads them. Vinyl or CDs without barcodes have to entered manually or via websites, like Amazon, etc. Readerware spells out all details of product in a user-friendly manner.
