Oops, a silly bug:

That should be pathname, of course:

    subprocess.call(['ffmpeg', '-i', pathname, str(track)+'.mp3'])

Also, be aware that the order of files coming from listdir is not 
guaranteed to be sorted in any specific fashion, so if you're renaming 
files like "3 blah blah blah.flac" to "7.mp3" you may end up a little 
confused :-)
