Audio track ripper given the tracklist

[pabloab]

This is a postprocessor feature request.
Right now we can extract audio track and rename it beautifully with youtube-dl --output "%(title)s.%(ext)s" --extract-audio --audio-format mp3.
It is pretty common to find Youtube videos which are full albums, not just one track. Is also very common to find on description the tracklist, in the form hh:mm:ss author - title\n
Wouldn't be really useful to have a --audio-rip or --rip-from-descrption option to rip those big audio tracks into their components?
Meanwhile I'm trying to do a bash script to do it manually, maybe with abcde.
