Just so you are not alone, played this on PS3 and Xbox, and no matter what was done your scores will keep for only, like, 100 songs. It sucks, but that is just the way of it and, I wish it was different, and it would remember all the songs, so you could play ones that you haven’t done, but whomever coded this game and the way they decided that there should be a 3000 song limit, and all the other stuff was incredibly short-sighted. I hear ya.
