Joining mp3 files

I have a collection (about 100 files) of mp3 files that i wanted to join together, well join together in smaller groups of about 14. I was about to look for an application to do this but being a fan of using command line I was drawn to investigating if it could be done using Mac Terminal and the command line.
I found the following little command would do the job, and did just fine.

cat * > new_file_name.mp3

Navigate, using terminal or similar command line tool, to the folder where all the files that are to be joined are stored. Enter the command cat * > new_file_name.mp3 and hit enter. There you go that is it. A few seconds later you have a file in that directory that is all the other files joined together.
Something to note is that the * will join the files in order they appear in the folder. If you files are not in the correct order then you will need to use the following –

cat part_one.mp3 part_two.mp3 part_three.mp3 > new_file_name.mp3

I have not used this last action but please let me know you experiences.
