Overstream your favourite song

I have added subtitles to this video, it is really easy but I feel really proud of it.
You can do it if you feel like,
just follow the link to overstream website.

First of all, you need to register..
Then  click on "create overstream"
you need a video URL, the one that you want to subtitle, you just copy and paste the URL
Anyway, there is a 90 seconds demo that shows you how to do it.
It is easier if you start with a slow song.
And never forget to save your work.
Try it and tell me how it was. Good luck!
