@Dan > The way I see it you have 3 options;
1) Upgrade your gear - possibly the most expensive option but you get all the new technology that can access USB storage and facilitate in categorising and tagging your files.
2) Buy a DVS system - timecoded discs for use with your CDJs that will allow you to play tracks on your laptop just like normal CDs. A somewhat expensive method (and possibly outdated).
3) Keep burning discs.
Hope this helps.
