It is really unclear what is required. Is the list_file variable or the output file?
You could try something like this and adjust as required...

Code:
f1() {
  :                             # put your function here
} 

[ $# -eq 1 ] || exit 1          # exit when no file provided
outfile=$1                      # this is the file that the user provides on the command line

while read line; do
  case $line in               
    \#*) echo "$line"           # Skip the comment
         ;;
      *) set -- $line           # split $line into positional parameters
         f1 "$@"                # call f1 with the positional parameters
         ;;
  esac
done < list_file > "$outfile"   # read from list_file, write to $outfile

qmp3join

qmp3join(1)							 quelcom man pages						       qmp3join(1)

NAME

       qmp3join - join mp3 files

SYNOPSIS

       qmp3join [option]... file1 file2...

DESCRIPTION

       qmp3join reads a list of mp3 files and joins them in one mp3 file in the specified order. some conditions must be met for the parameters of
       each of the files (see NOTES section).

OPTIONS

       -f, --force
	      force join bypassing bit rate checks. by default, to join two files they must be both vbr (have variable bit rate) or have the  same
	      bit rate. using this option you can skip this check.

       -h, --help
	      show a brief help and exit.

       -o <outfile>, --output=<outfile>
	      outfile  is  the name of the file where all the frames will be copied. if this option is not used, the frames from the second to the
	      last file of the list will be appended to file1.

       -v, --verbose
	      show which operations are done.

       -V, --version
	      show version and exit.

NOTES

       (all) the following parameters are required to be common for two mp3 files to be joined: [fill this!!!]. also, about the bit  rate  parame-
       ter,  both  mp3	must  have  the same value or (both) must have a variable bit rate. this restriction would be by-passable with the --force
       flag.

       before joining, all the streams are tested for validity. this is a time consuming operation.

       in any case, qmp3join can be viewed like a better but restrictive cat for mp3 files, due to the mp3 file format characteristics.

BUGS

       tests have been done only with mpeg version 1 layer iii streams, though it may (or not) work with other versions/layers.
