A very bizarre subset of the population enjoy reading reviews for some reason. Either to: tell them how to feel about something, to validate their own opinion because they lack social company in real life to do so, or because they enjoy it as a weird form of content in and of itself.
But if you're just looking for new music, PF's old curated playlist on their site was obsolete the second Spotify started curating it's own genre playlists.
I think it's the combination of the rise of accessible playlists AND P4k's review style. Many who read P4k just to find new bands, viewed the review style as an impediment, not a benefit, and left once there were better alternatives.
Personally, I left after the whole Black Kids debacle, where they overhyped, and then trashed, a promising young band and destroyed their career.
