Maybe it's just me, but when I stream the music, it sounds... weird. Like, kinda muffled, or more "mono" than "stereo". Stuff that I have downloaded, though, sounds fine. At least that's how it was on my Thunderbolt; haven't really tried music on my Nexus yet. I dunno, maybe I was just imagining it, though. *shrug*
Make sure you have the box checked to stream high quality in your settings.
