Good to see there is a radio option for those who like that option. However, using the updated version, the features/options/services for managing and listening to your existing music have been significantly deprecated on the player.
Why did this happen?
Google Music was one of the better apps out there -- maybe even the best one -- to listening to your own music. The library management, syncing, and especially the "instant mix" feature were all top rate.
Now, they're barely there. You can't even buy music from the app anymore. Imagine -- a music app where you can't buy music? Sounds absurd, but, here we are.
I can see on the Google Play support forums that many others are up in arms about these changes.
I have to ask, what was the rationale behind gutting the existing Google Music App in order to tack on this radio player? Why not just make a separate app? Or at least a separate division in the app specifically for radio?
