[gduns - with the Lord]

Not using Mp3+g files, you could follow the patterning I use on my mp3's (tho still time consuming.

I have a directory named artists.
under this directory I have folders named for the artists ie:
Alabama
Blood Sweat and Tears
and so on

in each of the folder I put the songs by that artist and they are named by the song title.

that would be easy for a program to pick up and set up a structure for.
