Neat
I oughta check out the audio books. It sounds like it's finally soup.
Compression usually sacrifices frequency response. Note that speech requires a limited range of frequencies compared to music, so you can probably get away with high compression of audio books and not lose a thing.
The track-naming thing is standard for CDs, and I can see that it must be a pain to have to rename them. You might want to copy each CD into a separate folder to keep them in the right order: "cd01/Track one", "cd01/Track two"...."cd02/Track one" and so on.
Glad I could be of service, Bowser.
