Using a barcode scanner might be an option. It' faster than inserting each CD in the CD player at least.

There is an option for this in OCD: From the OCD menu select 'Album | Scan UPC barcode....'

However, I haven't tried it out properly. As far as I can see OCD only allows you to pass the barcode to Amazon sites (American, British, German and Japanese). So if your CD collection contains titles that are not on Amazon's lists, you're out of luck.
