— I don't have Flash, so I download every video on Youtube. Most (all?) Youtube videos have mp3 audio, so with mplayer and dumpaudio I can get the music alone. I don't write shell scripts often, so this looks funny, but it dumps 120 MB worth of audio, and sets the ID3v2 tags correctly in 5 seconds. Ah, modern technology. Got to love it.
