Nirvis (www.nirvis.com) makes a very inexpensive solution -- $179.99 that uses Escients database via a lisensing agreement they made with CDDB prior to Escient purchasing it.

The graphics are not as pretty but it is functionally the same thing. You can even inter-mix MP3 and CD tracks/discs into a playlist you can save/retrieve.

The equivalent Escient systems sells for about $2500 (with a PC).
