I just replaced my 822 with an 8x (awesome, btw). Of course, I put on some apps, but have not connected it to my computer yet. I have Win8 on my computer and thousands of songs. When I look at the music on my phone, it looks like a lot (not all) of my music (streaming) is on my phone. It's not that I really mind, maybe even kind of cool, but it just seems weird. I have all the default settings and probably it's because the Xbox cloud collection switch is ON. No need to discuss the zune vs. xbox music here, as there are plenty of threads about that, haha.
