Different critics listen through a different set of filters. Yes - good music is good music - but we can't seriously expect a jazz afficionado to give a high standard critique of, say, an operatic performance. Especially when comparing one performance to another. Which is one reason Carpenters are often given the pariah treatment by rock'n'rollers. Quite often they just don't get it! For some, it might even be torture listening to Karen at Christmas. Who knows? Should we care? I say 'no', even though it's interesting to hear what they have to say. Ultimately, I believe the best critic is one who has both a generalist's ear for music and a specialist's ear for the genre. In relation to the Carpenters' music, it's quite possible the guys at Rolling Stone have neither.
