Bieber over Bowie is just a reflection of society as a whole in the last decade. Barack Hussein Obamas' Nobel Peace Prize for doing NOTHING up to that point, was just the beginning of the end for relevance in life. A sports figure getting a multi-million dollar contract, on potential, that blows out a knee, yet is still revered.
Todays' generation only sees today, and no longer needs to pay attention to the history that got them to where they are is but a symptom of a society that puts value on nothing. THAT is why the music industry sucks.
