Command line mp3 file joiner?

Hi all,
Hoping someone more experienced with command line utilities can lend me a hand. Right now I have Hazel take mp3 files of mine and copy them into a certain folder. I'd like to have those mp3 files joined up into one mp3.
I haven't found much in the way of applescript or automator tools to do this, but I stumbled upon a command line utility called mp3wrap. It's pretty simple. They say all you have to do is type in the following command line: "mp3wrap album.mp3 file1.mp3 file2.mp3".
Question I have is how can I have Hazel do that? And is this the easiest way? Has anyone been able to merge mp3 files together?
Thanks all!
