Audio copy all chapters at once in multi files.

I have some "musical" movies and concert movies that I would like to rip just the music part into MP3 files. Rather than audio copy each chapter 1-at-a-time, I would like to capture them all (ie: Chapter01.mp3, Chapter2.mp3 etc.). The titles could be taken from the actual chapter titles. Then I could pick and select the songs I want for editing (editing OUT non music audio) and entirely skipping chapters without music. I COULD do all this very, very slowly by watching the entire movie at normal speed and capturing desired audio it using Audacity, but that is quite tedious. I would also hope that the copying of just audio would very fast.
