Amazon Prime music on Chromecast Audio?

Does anyone know of a workaround for this on Android?

I suspect I can cast from my browser on PC, but is there a way of doing it from an Android tablet or phone?

I find that Amazon insists on installing their app, rather than go through the browser, which won't play with Chromecast.

I have a Prime sub, and don't listen to enough music to make it worth having a separate Google Music or Spotify subscription.

In case anyone else is trying to do this, I've not necessarily figured out a solution as such, but have found that my Nexus 7 (2013), running Android 6.0.1, can cast its entire audio output to Chromecast audio (swipe down from home screen to find the cast button). So can now cast Prime music to my Chromecast.

I assume this is a Marshmallow additional function, rather than something specific to the Nexus 7, or other Google devices. None of my other Android devices can do it, but are all running older versions of Android.

For those, I would need to root the device, and install a third party casting app which will do the same job of casting all sound from the device. I might try it on my old Hudl 1.
