The problem is the now playing layout. The artist name needs to be on it's own line and the font sizes need to be reduced. Also, the ID of the caster doesn't need to be displayed (or at least could be much smaller).
Please note, the now playing screen of the Pandora app on Android (TV or phone) is just fine. The display issue is only when casting.

Some things for your UI designers to think about: The now playing display is different on Android phone, Android TV app, and casting to Android TV. Shouldn't they all be the same or, at least, very very similar? And why would one ever think it's a good idea to put the artist name and album name on the same line?
