In most cases how this concept works?
What do people exactly mean by "underrated" when it comes to certain bands and is that term used in the right way?
I think this term is mainly subjective. If some bands were very good (in subjective sense) but they weren't lucky to make it big and get recognition, does it make them underrated(For example, is Camel underrated, is Budgie underrated, is Blue Oyster Cult underrated, is Hawkwind underrated, etc?)? And if people call those bands underrated, they cannot determine BY WHOM they're underrated?
Is underrated a valid critique of certain bands?
What do you think?
