Sony BDP-S370 - mp3 track time length?

I was curious if it is possible to see the total track length time displayed for an audio file. It shows elapsed time, but it doesn't seem to want to show the total length of a track. I thought maybe I am missing something simple. The "display" button on the remote doesn't appear to change anything for the audio display, though it does work if you want that information for video.

It gets send to the player, so it probably chooses not to show it - unless someone with the player can point you in the right direction.
