download all files on a page easily with this firefox add-on

loving all the free mp3s on the web but hate having to manually download each and every one of them? flashgot lets you download all files on a page with one click. i haven't tested it enough to know how it handles other linked files (such as html webpages)--if you have any great discoveries with it, post 'em in the comments.
