yeah, that one!

download it, then upload it into your recording software (if you don't have one, you can download audacity or kristal for free) and then either using a mic infront of your amp, or plugging in direct to your soundcard, record over-top of the backing. some people have the backing dominating because it's alot harder to control your volume using a mic, so I recommend recording direct for now until you have decent enough gear to accomodate mic recording.
