Can I return to my queue from radio?

I often queue up many songs/playlists to listen to. Sometimes I switch to radio, such as the Discovery station. There is no way once I'm in radio to switch back to my play queue. If I start playing a song from the library, my queue is wiped. The best solution to this is to instead completely restart Music, since it always starts up in the library view.

There doesn't appear to be any way to switch back and forth between the queue and radio. Am I missing it?
