I was looking for the song Also Sprach Zarathustra.
But I could only easily found it as video http://www.youtube.com/watch?v=SLuW-GBaJ8k.
After a quick search I found out how rip the audio from a youtube video (via linux/fedora):
1) Download a video from youtube
– yum install youtube-dl
2) Extract the audio track
– ffmpeg -i nodame_theme.flv -ab 128 -ar 44100 nodame_theme.mp3 (thanks to http://linux.byexamples.com/archives/229/extract-audio-from-video-or-online-stream/)
3) verify and play your file 🙂
That’s it folks!
