My friends and I play, and I bought 1 and 2 for my brother this past Christmas. I play when ever I can I haven't been able to play much this year b/c my classes have been crazy busy, but when I do play, I can play medium pretty easily and was working my way through hard when I was at home last. I eventually had to just start leaving my hand on the lower four, b/c it's easier to move your pointer finger than it is your pinky. Works for me at least...once you start remembering when your hand is ^_^

I love Guitar Hero, but I have to say, Rock Band owned my face.....I wasn't cut out to be a drummer
