Nokia Mix Radio - Number on Live Tile - Whats it Mea?

[Smyrna5]

Sorry if this has been posted or is in a manual somewhere, but I have googled it and keep coming up with nothing but all kinds of extraraneous crap. So, what does the number on the live tile on Nokia Mix Radio mean? I'm running Black since I am one of those poor unfortunate T-Mo customers waiting for Cyan.
