Is RadioTuna really the only the embeddable webplayer widget that automatically fetches and displays album cover art of what's playing now on the fly? It's very cool as it negates the station's need to maintain its own art repository which saves a lot of work. Just one small hitch, when RadioTuna plays within a web page for too long, small (very minor) stream interruptions occur probably due to local cache issues (which many web players experience).
So, if you folks find any other automatic now playing album cover art solutions I'm all ears.
