End-To-End tutorial: extracting audio from YouTube video

My friend asked me how to extract audio from a You Tube video, so here's the step by step instruction.

1. Find the YouTube video that you want to extract audio from.
2. Copy the URL of that page.
3. Paste that URL in the textbox of the page FLV Retriever . Click the button, and you will get the actual video link.
   
4. Copy that link and paste on the browser, and download the video file.
5. Once downloaded, add the .flv extension if the file doesn't have it.
6. Now download the tool FLV Extract . Run it, and then un-check all except the audio.
   
7. Drag and drop the .flv files on FLV Extract application.
8. the .mp3 should be created in the same directory as the .flv file.

Mission accomplished.

(Last update on May 19 2008) : The FLV Retriever doesn't seem to work anymore. Instead, use the Video Download tool at TechCrunch instead.
