Rename some files

find the files like this: find ./ -type f -name "*.mp3"

Pipe them into a loop: help read help while

find ./ ... | while read original ; do
  newfile=$original
  echo $original $newfile
done

It might be easy to use cut:

newfile=$(echo $original | cut -d'-' -f 3,1,2,4-)
# you can pipe commands as many as needed.
newfile=$(echo $original | cut -d'-' -f 3,1,2,4- | cut -d' ' -f 2,1- | tr -s ' ')

When happy with the results, replace echo with mv.
