Radio Display When Playing SD Card


That display is saying something about the current song. It changes for each song and is always the same for each song. Nothing to do with a playlist. I thought perhaps it was BPM indicator, or sound level or something else specific to a song, but haven't seen any of that hold true. Thought maybe somehow related to "equalizer" setting in the track or something, but don't notice that either.
There must be some document somewhere explaining this!
