What's the deal about being pretentious?

I agree. And yet I hear people say they are proud that prog is pretentious and that they listen to pretentious music.  Either I've got the meaning of pretentious all wrong or it's a much abused word.   I do find classical-crossover kind of stuff pretentious but I would concede even there that it could be argued to be a matter of preference.  If somebody wants to listen to pop-ified versions of classical songs and if the artists in question market it as 'classical' or 'sophisticated', let them.  It doesn't really matter...at least, not anymore.
