Just a note on the above; the "ls" is completely superfluous.  The shell is
already expanding "*.mp3" to the list of all mp3 files in the current
directory; ls would only be necessary if you wanted to extract file
information other than the name.

for i in *.mp3; do .... done has the same effect as the above, but it avoids
launching a subprocess and the ls program.

You often see people writing stuff like 'ls *.bar' when 'echo *.bar' would
have exactly the same effect but would be considerably faster.
