Ok, first off, I REALLY appreciate the help. And sorry if I am not explaining myself well.

This is what I am looking for... using a small portion of my test directory, we have (making the songs up, since I am work and don't have access to my box at the moment):
/usr/test
/usr/test/W
/usr/test/W/Wall of Voodoo/mexican radio.mp3
/usr/test/W/Wall of Voodoo/another song.mp3
/usr/test/W/Wall of Voodoo/third song.mp3
/usr/test/W/Wall of Voodoo/Dark Continent/dark continent.mp3
/usr/test/W/Wall of Voodoo/Dark Continent/light continent.mp3
/usr/test/W/Wall of Voodoo/Dark Continent/grey continent.mp3
/usr/test/W/Wall of Voodoo/WoV Live/mexican radio.mp3
/usr/test/W/Wall of Voodoo/WoV Live/lola.mp3
/usr/test/W/Wall of Voodoo/WoV Live/freddie.mp3
The output I am looking for is:
/usr/test/songs.m3u
/usr/test/W/songs.m3u
/usr/test/W/Wall of Voodoo/songs.m3u
/usr/test/W/Wall of Voodoo/Dark Continent/songs.m3u
/usr/test/W/Wall of Voodoo/WoV Live/songs.m3u
The contentents of /usr/test/songs.m3u would contain all mp3s found in subdirectories below it. /usr/test/W/songs.m3u would contain all songs in subdirectories under /W. /usr/test/W/Wall of Voodo/songs.m3u would contain all songs in subdirectories under it, etc. For this example, the output of all 3 files would be exactly the same though, since I didn't include other letters (X,Y,Z) or other bands (Who, The).
/usr/test/W/Wall of Voodoo/mexican radio.mp3
/usr/test/W/Wall of Voodoo/another song.mp3
/usr/test/W/Wall of Voodoo/third song.mp3
/usr/test/W/Wall of Voodoo/Dark Continent/dark continent.mp3
/usr/test/W/Wall of Voodoo/Dark Continent/light continent.mp3
/usr/test/W/Wall of Voodoo/Dark Continent/grey continent.mp3
/usr/test/W/Wall of Voodoo/WoV Live/mexican radio.mp3
/usr/test/W/Wall of Voodoo/WoV Live/lola.mp3
/usr/test/W/Wall of Voodoo/WoV Live/freddie.mp3
The contentents of /usr/test/W/Wall of Voodoo/Dark Continent/songs.m3u would be:
/usr/test/W/Wall of Voodoo/Dark Continent/dark continent.mp3
/usr/test/W/Wall of Voodoo/Dark Continent/light continent.mp3
/usr/test/W/Wall of Voodoo/Dark Continent/grey continent.mp3
I actually eventually have to turn all the ' ' (spaces) into '%20' but I think that will be simple versus getting the songs.m3u files built.
From you example below, it looks like it might be possible to have the songs.m3u file actually be named after the last directory (W.m3u, Wall of Voodoo.m3u, Dark Continent.m3u) by probably using a command similar to -maxdepth flag, but songs.m3u is more than fine... I can find how to do that later.

ls is the wrong tool for listing filenames with the path. So the only
case it works for is when all you want is files in the current
directory with the path relative to that directory (i.e. - none). Find
always lists files with full path information. So we create playlist
by the path information off - being careful to preserve multiple
spaces in the names. To get names relative to the current directory,
you cd into that directory and run find (or ls for 1a) just putting
the output in the playlist. Whether you start the outer find with "."
or "/mp3dir" is irrelevant, because the inner find is going to start
at "." after the cd. To get paths relative to the top directory, you
run the outer find on ., the inner find on the directory name, and
redirect the output appropriately. To get full paths, do the same
except that you start the outer find with the full path. If you want
to keep find from descending into subdirectories, use "-maxdepth 1".
If you need option 3 or d, it's going to wait until after I get some
sleep.
