Absolutely.  I try to do that in any case, even in non-GUI.

It's planned to be a database for data CDs, rather than audio ones; the
main advantage over the many DBs I've already encountered is to store an
MD5 checksum of the file, so that I can check to see if a new file I have
is a duplicate of something I already have and have archived off to CDROM, 
without having to find the CDROM.

I've also thought of having a twist here for MP3 files, specifically,
distinguishing between the files' audio frames and identification info
frames, and checksumming only the audio portion; so that two otherwise
identical MP3 files with different ID3 data would nonetheless have the
same audio checksum and show up as identical; but that's an idea for the
future.

I've also thought of, for image files, to store a thumbnail in the
database, too.

In any case, dabbler that I am (and given the fact that I have two
daughters, one 2 years and one only 3 weeks, which substantially cuts into
my hacking time), I'll probably finish this up, oh, sometime in 2008.
