Listen and download music with Mp3Tube

I recently found Mp3tube, a site that lets you search music and listen online right away(I've posted other sites like this one on previous posts).
Here is the link: http://www.mp3tube.net/

I also found a Greasemonkey script that allows you to download the songs:
