HOW TO RE-PLAY A SONG / VIDEO FROM YOUTUBE IN A LOOP

I just learned something.... Did you know that if you find a song that you like, (or something else), on Youtube that you can loop it to play again and again? All you have to do is go up to the web address at the top of your page where it says ; http://www.youtube.com/

.....etc... and type in the word 'repeat' between youtube and the .com so it now reads: http://www.youtuberepeat.com/

..... It will bring up a page that will link to your youtube page and it will repeat as long as you would like!
