Nope.
Millions of people can quite conclusively be wrong.

Are you feasibly trying to make the case that, say, the Mr Blobby song, or Wet Wet Wet's version of Love is All Around are of the highest quality? Because they clearly aren't.

The phrase 'lowest common denominator' springs to mind here.

EDIT: I am in no way implying that obscurity equals quality either, that would be silly. Some obscure stuff is great, lots is obscure for a reason.

Yes, just because I don't agree with it doesn't make it less valid.
You're putting your opinion above not only another person but over thousands or tens of thousands of people.

We all do that to a certain extent though.
And I still can't understand how one can equate mass popularity with quality- the two are hardly linked at all. In fact, dumbed down stuff sells in vast amounts, just look at ITV's output. Are you making the case for X Factor over The Thick of it?
