I find the Google Music App for Android to have a reasonable design... not great, but usable. What I can't deal with is the fact that just like Amazon, it never seems to have occurred to them that you might have a large music collection, and it's insanely slow at times, sometimes taking 10s of seconds to respond to a tap. You're right about the downside of streaming. I used to use Amazon until they killed their Cloud Music capability earlier this year, and I switched over to Google. Both services provide a lot of value, but in both cases my number 1 request would be to somehow allow third-party apps to access the cloud because the built-in apps are pretty awful.
