assuming that your MP3s are in /music/mp3:
chgrp -R music /music/mp3
--> this recursively changes the group of the files to 'music'
chown -R pierre /music/mp3
--> this recursively changes the owner of the files to 'pierre'
these two can be combined:
chown -R pierre.music /music/mp3
then you should make them accessible to all in group music:
chmod -R o=rwX,g=rX,o= /music/mp3
and you are done.
one warning:
NEVER, i repeat *N*E*V*E*R* use the -R flag to chmod/chgrp/chown if
the final argument is not a directory. for instance
chown -R pierre /music/mp3/*
will eventually change *your entire filesystem* to be owned by
pierre!
