I'm a great player at Medium (with a guitar, Drums I suck and I don't have the balls to play Vocal), but Rock Band won't let me progress at a faster pace unless I get some Hard Mode play time. At least I can finish songs. But right now I'll stick with Medium for an answer.
Edit: This probably would have been better suited for Gaming Dis. in hind sight, but whatever.
