Show Play Music's 'now playing' notification on Windows PC

At my desk, while working, I typically stream music from Google Play Music (GPM) using my Chromecast Audio device linked up to my hifi. I control this via my Samsung Galaxy S5. What I'd like is some way to display the 'now playing' track on my Windows 10 laptop (as a widget or notification, preferably), as this is the screen that occupies my attention; I don't want to have to divert my attention from my work in order to turn the phone screen on every time the track changes. Is there anyway I can accomplish this (I could conceivably script something if there was an appropriate API, but there doesn't seem to be). Or a way to send that info from the phone to the laptop?
