Many people wonder how you listen to a youtube song on repeat. Well, right now YouTube does not provide an easy solution. However, here's how we do it:
1) First, find the youtube video you want to watch on repeat and copy the URL into your browser: http://www.youtube.com/watch/?v=rIUSikXex5w
2) Add the word "repeat" after the word youtube in the URL: http://www.youtuberepeat.com/watch/?v=rIUSikXex5w
You will then be taken to a different website which allows YouTube videos to be set on repeat. A very nice service.
