Greasemonkey - "Amazon Free Music" helper

Amazon has lots of free non-DRM music available here It is a pain to click through to download, so I decided to write a quick userscript for Greasemonkey which skips the step of having to click to another page, and lets you get the music. Clicking some of the music results in amazon saying: "We're sorry. The track you requested isn't available." This is not a problem with my script, but Amazon limiting the number of downloads or something. There has been talk that they may limit downloads to non-USA users.

Update

I've converted the Greasemonkey script to be a extension, so you don't have to install Greasemonkey if you don't want to (although there are many more things one can do with it) You can install either of:

Firefox extension: amazon_music_helper.xpi (you have to allow firefox to install extensions from overstimulate. the first time you click it will say you are not allow, change the options to say you are allowed, then reclick the extension to install)
Greasemonkey version: Amazon Music Helper - requires Greasemonkey

ps. I offer my services building custom greasemonkey scripts
