I haven't read the WSJ articoe but what type of a weirdo uses metacritic for album reviews?
I guess the reason that bad reviews don't exist anymore is that they became redundant now that all new music is represented in some way or another online. I think it serves fans best to have music reviewed by people who are interested in that type of stuff and if what they say sounds intriguing you can check it out for yourself within a few seconds of reading the review. The new bad review is an indifferent review.
I'm glad the days are gone of magazines getting people who don't like a thing to review that thing. It is a waste of everyone's time.
