I agree. Never go backwards and try to re-create the music that made you the star today. Well that's what i think
I think The Fame was very much a self contained era. I don't think its right for her to know go back into it. I suppose one of the problems Gaga has though is that she has done so many different image styles in such a short space of time that there is little for her left to really work with. So repeating some things was going to happen. Perhaps she shouldn't have been so full on that early in her career. Holding some ideas back for later albums would have been more wise.
