The tools you need are described on [blog.joff3.com](http://blog.joff3.com/2008/02/downloading-and-ripping-music-from.html).
There's also the nice [youtube-dl](apt://youtube-dl) package. One thing I noticed: the `ffmpeg` command there re-encodes
the audio which might loose some quality. To just dump the audio off the Flash video, use:

    ffmpeg -i somevideo.flv -acodec copy output.mp3

This is for 240px videos. All larger ones use AAC format. Use this:

    ffmpeg -i somevideo.flv -acodec copy output.aac
    ffmpeg -i somevideo.mp4 -acodec copy output.aac

If you happen to have the latest webm format, use this:

    ffmpeg -i somevideo.webm -vn -acodec copy output.ogg


This will just extract the audio track without doing anything to it.
