I meant nothing of the sort.Er you mean people have different musical taste to you and liking Rumours indicates nothing one way or the other about musical knowledge. The facts generally are against you as someone else has already posted and indicative that perhaps your musical knowledge is lacking given the critical standing and popularity of the album makes it a top album in every sense.
They have no musical taste, couldn’t really have made myself any clearer I thought?
Just because lots of people bought may be a fact, but it doesn’t make it a great album, nor does it make the gazillions of buyers anymore knowledgeable. Probably bought it knowing other sheep had too.
