Why not add CD copying and CD buring features?
Many users, besides cataloging, need to digitize their collections and
later on copy them as a backup, as a present or whatever reason maybe.

As a whole I would split the product according to the audience:
home and advanced (or whatever the name may be) as they do it with other software.

At the data entry stage the CD copying functionality is obviously lacking.
At the presentation stage there should be such features as playlist compiling, playing via barcode, assembling a compilation and CD burning.
