To do HQ...
Step 1: Go to a proxy website that works with this little trick.
Step 2: Go to the File2HD site from the proxy site you find.
Step 3: Put the band's Myspace address in the box, set it to Audio and agree to the terms of service and there you go.
Now, it's best to save them as .MP3 downloads and not HTML files when it prompts. If you only get 4kb of the song, then the proxy isn't working and you have to try another proxy site. It doesn't always work.
P.S. I don't condone the use of this service for stealing music from artists who work their butts off to do music for a living (I'd know, I'm one of them). If you like the music, please consider paying for it.
