This is getting a bit more subjective, but I much prefer the Zune Marketplace. The interface is colorful,  has more flair, and certain cool features similar ‘Mixview’ that allow you quickly see related albums, songs, or  other users related to what you’re listening to. Clicking on one of those will center on that item, along with  another set of « neighbors » will come into view, allowing you to navigate around exploring by similar  artists, songs, or viewers. Speaking of users, the Zune « Social » is as well enormous fun, letting you find  others with shared tastes and becoming friends with them. You then know how to listen to a playlist created based  on an amalgamation of what all your friends are listening to, which is as well enjoyable. Those concerned  with privacy will be relieved to know you know how to prevent the public from seeing your personal listening  habits if you so choose.
