Mozz - // Andy, I think you're focusing on the wrong aspect of this endeavour. It's quite possible that the residents were given a bunch of album covers and were allowed to pick whatever they wanted to do. //
I have no issue at all with what was done - just the notion of referring to 'classic' album covers.
That's fine, if you confine your selection to classic album covers, if not, and clearly this was 'not', then just call the popular album covers or favourite album covers, or just album covers.
If you are going to call something 'classic', then it needs to fit the description, and several of the albums did not.
It matters not one jot to the vast majority of population, but when you have the love of music that I have, it matters a lot.
