don't you know that all media is socialist/leftist today? Newspapers, tv shows, holliwood movies, music (also seen on MTV and VIVA). Music is just a mirror of society's current state. It represents the trends.
Video games are the last bastion but they will fall in less than 5 years as the already brainwashed consumerists are now the major markets for new games (look how FIFA / NHL / Battlefield / Call of Duty get a new release every year with minor changes and people buy it for the full price). Gaming was once a tech enthusiast hobby but now it is gone mainstream since the PS3 and things that go mainstream become shit.
