What does it mean when the letter N appears (in upper case) in front of the Artists Name while a track is playing? Sometimes this appears for a few tracks then goes away and the play symbol returns. This N also appears on the second line under the Bryston BDP-1 when the player is turned on and booting up.

Example:

Snowbound
NDonald Fagen

And:

Bryston BDP-1
N

I'm using MM S2.06 2014-10-07.
Thanks
