Try uninstalling the app, removing the device from approved devices in Google Play Music settings, reinstalling the app. Pretty sure that's how I fixed the FC on 3G error this past time.
I tried your suggestion, and it seemed like that might have been one issue, because Google had two of the same phone listed. I uninstalled the app, deauthorized both of them, and then reinstalled (multiple times, each time trying a reboot in between or not).
However, I am still getting the error "Unfortunately, Google Play Music has stopped." and then it FC's. It happens only when I'm trying to stream something. It even starts to load the song part way but still brings up the error. Yet if I switch to wifi, no such problems. Then, this is where the weirdness happens. If I turn back off wifi, after partially loading one song, the 3G works for a while. Earlier, when I encountered this strange behavior, it stayed working for a few songs, but then when I tried again later, it FC'd again. It's a bit odd, but since I have a partial workaround for now, it's not too bad anymore, as long as I have a place for the initial wifi.
I just did a reboot while it was working under 3G via that method, and it appears that on a fresh boot—without wifi on—it still does not work. Again, the wifi-switch method continues makes it work. I am perplexed.
[edit] I'd like to add that most everything else (besides the lack of camera preview) has been blowing me away. To me, there are only a few big bugs that I'm working with.
