No Genie, you do not have to register. I didn't even have to register to use it.

When you click the link and the page opens, scroll to the bottom and look at the right sidebar (more like the right half.) At the very bottom, on the right, there is a message that says something like "Please wait to download", and under that, in red lettering, it counts down from about 50. Then it will say "click here to download" or something like that. On my Mac, the little download window pops open, and once the file is downloaded, it starts to play.
