"Nokia Music" changes to "Mix Radio"

I'm surprised I haven't seen anyone comment on this yet, but what are your thoughts on the new Mix Radio which has replaced Nokia Music? I certainly think the UI looks nicer, but other than that it doesn't seem all that different, I assume the change was made because of the Nokia acquisition, but I'm not displeased by it. A question to any previous users, did your music transfer over? I wasn't a heavy user of Nokia music and primarily used Xbox music, so I'm not too sure about what happened there.
