I don't know that it can be downloaded.
I know I've explained this in past posts. Open an audio editor, I would use
SoundForge. Go make a NEW file, 44100 stereo. It brings up the record editor.
Go to Windows sound settings. I have an icon on the taskbar, but it's not there by default. You have to enable the icon in the Windows sound settings in control panels. Anyway, turn off everything but master, WAV, and then the "what you hear" type setting. The name varies from card to card.
Anyway, with this "what you hear" type channel selected, music pumps from the webpage into the sound input channel, then to your output channel. While it's going through the input, you can record it.
Hit the big red record button in
SoundForge.
This is how I got some soundtracks to CD, off their myspace site.
Sometimes downloading is not just impossible, but unnecessary too.
And you're right ... it is cool.
