I think Rumours was released just about at the peak of their acceptability, I think its a well crafted album made by a band who were just peaking ,albeit they were also just falling apart.So many of these crap not crap threads are really difficult to comment 30 years on , in hindsight I can find lots of reasons to vote crap but at the time I would have voted Not crap , even though 1977 was a year that turned music on its head .The footage of Rhiannon used on OGWT is a classic.
Not Crap but I wouldn`t expect anyone under the age of 40 to vote this way.
