I'm having a really hard time getting this achievement. I can't get it locally, because I don't know anyone thats good at rock band, which leaves me having to go online to try and get it. I've played multiple sessions of xbox live quickplay, and the closest I've gotten is 840k on Sgt Peppers Lonley Hearts Club Band, with a full band (me on expert and the other three on medium). There seems to be a lack of expert players playing the game, and theres lot of medium/hard players who keep missing notes, don't activate overdrive, or just don't know that it's important for everyone to activate at the same time for the maximum score. Anyone else struggling with this achievement?
