Some comments on your code snippet:
Code:
files=(ls *.mp3)                # this will define & assign an array: (ls a.mp3 b.mp3 c.mp3 ...). You'd need to use it like an array in the for loop, then. 
                                # you might prefer command substitution: files=$(ls *.mp3)
                                # or let the shell do the work for you: files=*.mp3
for song in $files              # this will expand to the first array element: ls. If you want the .mp3 files as well, use array expansion: ${files[@]} if you don't like above proposals
 echo "${song%%*(.mp3)}"        # Why the * and the parentheses? You want to remove nothing but ".mp3", and once only, so one "%" is sufficient
 touch "${song%%*(.mp3)}"       # "${song%.mp3}" will do the job for you. "%*.mp3"  would erase the entire file name, the parentheses can't be matched
                                # and thus stop the expansion.  
                                # You are right in double quoting the file names which will handle spaces in file names, then.
done

  NAME
      dr_unsort - unsort the current mpd playlist

  SYNOPSIS
      dr_unsort

  DESCRIPTION
      dr_unsort invokes unsort(1) on the current audio playlist as used by mpd.  Use it if you'd like some variation in your music.

  EXAMPLE
      If The_Beatles/The_White_Album_I/03-Glass_Onion.ogg is the current playing track and your current playlist looks like

	Flying_Lotus/Los_Angeles/01 Brainfeeder.mp3
	The_Beatles/The_White_Album_I/01-Back_in_the_U.S.S.R..ogg
	The_Beatles/The_White_Album_I/02-Dear_Prudence.ogg
