Other than the stuff already stated, my only beef with Zune is the Zune Card. I was under the impression that the Zune Social would be so awesome that it would replace last.fm as my music social. But most/all of my songs don't appear on my Zune Card because my tags aren't perfect. Just copy last.fm and read the song title and the artist, and for the album art, have the Zune software upload a 90x90 pixel pic, its a small enough file. And the Zune software/hardware should display the contributing artists, for example, the artist field for the song Success from Jay-z's album is: Jay-Z; Nas. But the Zune software/hardware displays the album artist instead and just says Jay-Z.
It seems a lot of the users' issues with the new Zune software could be solved by allowing the Zune hardware be compatible with WMP11 (might as well add playsforsure support too). And let the new Zune software be for "lightweight" users and WMP11 for advanced users.
Go buy KiD CuDi's album!
