Ok before we start 252 of these albums are brilliant and Id quite happily stick any of them on. Down to 500 many of the acts have done better but these are all good listens.
Under 500 and these are all worth checking out but maybe more for completists.
But lets list the albums that I thought had a chance to make this list but against this competition were found wanting. I know some of these will have big fans here and none of them are bad, well maybe the first one
