I personally think this is a good thing. I think Google does a great job of getting utility out of their UX, and while this doesn't really do more than the utility of streaming music for the realm of competitors that it is venturing up against I think the more "non-google" it looks, the better. (Disclaimer: I have not used the android music marketplace, which I think might be closest to this area of design for Google of stuff they already had live).
