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

mp3cut

MP3CUT(1)							   User Command 							 MP3CUT(1)

NAME

       mp3cut - cut and assemble MP3 files

SYNOPSIS

       mp3cut  [ -o outputfile ] [ -T title ] [ -A artist ] [ -N album-name ] [ -t [hh:]mm:ss[+ms]-[hh:]mm:ss[+ms] ] mp3file [[ -t ...	] mp3file1
       ...]

DESCRIPTION

       The mp3cut utility cuts and assembles MP3 files according to the time specifications given on the command line. The mp3 output  is  written
       to  the	outputfile.  If  no outputfile is given on the command-line, the name for the outputfile is created from the name of the first mp3
       file by adding output.mp3 at the end. The -t flag specifies which part of the mp3 file following it will be extracted.

OPTIONS

       -o outputfile
	      Specify where the output is to be written.

       -T title
	      Specify the title ID3 tag for the output file.

       -A artist
	      Specify the artist ID3 tag for the output file.

       -N album-name
	      Specify the album name ID3 tag for the output file.

       -t [hh:]mm:ss[+ms]-[hh:]mm:ss[+ms]
	      Specify which part of the following mp3file will be included in the output file.

		    hh	= hours
		    mm	= minutes
		    ss	= seconds
		    ms	= milliseconds

	      If the starting time is omitted, 00:00:00+00 is used as starting time. If the ending time is omitted, the end of	the  MP3  file	is
	      used as ending time.

EXAMPLES

       mp3cut -o output.mp3 -t 23:42+500-01:23:42+750 input.mp3
	      Cut  the	segment  from  23  minutes,  42  seconds  and 500 milliseconds to 1 hour, 23 minutes, 42 seconds and 750 milliseconds from
	      input.mp3 and write the output to output.mp3.

       mp3cut -t 00:01-00:02 input1.mp3 -t -15:23 input2.mp3 -t 9:87+500- input3.mp3
	      Append the segments from input1.mp3, input2.mp3 and input3.mp3 and write the output to input1.output.mp3.
