It is obvious (to me) that there is not one display template appropriate for all music.
So I’m thinking what would be an efficient way to change templates with the music type? Genres came to mind.
Create 3-5 templates for chromecast/webcast and let the user assign them to different major genre types. One template could be clean and spare, another dense with information, and other variants. Or, the user might set the display to a random template selection for variety.
