Download mp3 from YouTube.com

1. hey today i am telling to how we can download mp3 of any youtube video just by adding a simple word...
2. you just have to add "sing" after "www."
                       
3. if the youtube address of video is   http://www.youtube.com/watch?v=P5NtHCpnC0g   then you just have to add sing after "www."
   like that http://www.singyoutube.com/watch?v=P5NtHCpnC0g
4. AND then a website open and ask you to which quality mp3 song you want to download of that video
5. select the quality and click on process then downloding will start automatically
   

in some schools and hostals youtube is blocked then you just have to search your video in google then just copy the adress of youtube and add sing after "www." then you can download its mp3 even youtube is blocked :)
