[luv-main] bash script

Anyone like to critique this script for grammatical efficiency and correctness? In particular the line indicated. I'm guessing I can do command substitution better than this. title="test" ls -1 *.mp3 > mp3.txt while read filename do echo $filename song=$title${filename:5:4} echo $song id3ed -isq "`echo $filename`" id3ed -q -s "`echo $song`" "`echo $filename`" <---- id3ed -isq "`echo $filename`" done < mp3.txt
