File2HD.com
This lets you download basically anything from any site, just enter the url in the box and press "Get files" Though when you have pressed it you only have about a minute to download the stuff you want, after that you have to refresh it.
I mostly use this for getting youtube videos or myspace music that's not up for download.
Enjoy! (sorry if it's in the wrong section, but this looked like the most suitable one.)
