Check what media is now playing from the command line

My desktop environment seems to know what music I am playing. I want to be able to check that from the command line too. Is there a tool or dbus query that will tell me what music or media is playing at the moment, and preferably what app it is playing in? The are many possible applications for this, but my actual use case is that I want to queue up playing some music from the CLI after a one hour music set finishes playing in YouTube on Chrome.
