WP needs Zune. Wrap it in an Xbox skin and call it whatever you want to call it, but the current Xbox Music/Video is practically worthless. I somehow doubt that WP8.1 will improve much on the current pathetic and cumbersome WP media consumption experience.
Yeah,I know, haters gon' hate but Zune spawned what we know as WP7 and it was just plain stupid to remove it from WP8.
