I'm listening to this (well this isn't right now per se, it's just the most recent one) by way of practicing it off of a Powertab print-out:
Not saying I'm great at playing it, but sometimes I go through it better than others ... I haven't been using a metronome, so that's a problem right there. Powertab has a metronome in it, but it doesn't work for some reason on my computer's administrator log-in, yet works just fine on the guest log-in ...
