Haven't really tried out all the features...I just absolutely hate the Music UI on Windows 8. They were somehow able to make music look incredibly boring. Where's all the color?

There's also no desktop application for managing music. WMP hasn't really been updated and doesn't connect to Xbox services.

The free ad-supported music works fine on my tablet but doesn't work at all on my laptop.

Yeah...I kinda hate it in its shape right now.
