It just does, no matter how it's advertised.

To see beyond this deceptively bland, relaxing facade, people would have to pay close attention to the details of the music. Much closer than with most pop/rock etc., since those usually have a simpler, immediately catchier compositional structure and therefore require less attention to appreciate.
Wait, didn't someone already say all that somewhere in this thread?
