With technologies today and hard drives costing around 60ukp for a 120gb
drive you'd be best hiding an old computer in the attic and encoding your
cd's as MP3 files.

Use an rs232 link or radio link to communicate with the PC and bobs your
uncle - no nasty mechanisms to go wrong, mp3 tag systems for identification
of the track and a lot of space saved.

You could even consider something like a laptop with an external usb hard
drive for this application.
