Or you could do it with perl and not have to do the escaping:

find ~/Music/ -type f -name \*.mp3 | perl -p -e
's|/Users/svante/Music/|/A-C/|' > playlist.m3u

and if you use three letter spacings for all your categories (ie: A-C is
for artists who start with that letter range followed by
D-F,G-I,J-L,M-O,P-R,S-U,V-X and Y-Z) you can try this:
 
find ~/Music/ -type f -name \*.mp3 | perl -p -e
's|/Users/svante/Music/(.*)|sprintf
"/%c-%c/$1",ord("A")+3*int((ord(uc($1))-ord("A"))/3),($b=ord("A")+3*int((ord(uc($1))-ord("A"))/3)+2)>ord("Z")?ord("Z"):$b|e;'

And it should do the directory classification for you. Not guaranteed
and certainly could be done cleaner.

Though you probably don't have 3 letters in each directory though. It's
not too hard to make it do arbitrary sized groups but it's well beyond
the scope of this email.
