I recently installed subsonic 6, and notice not all songs play. I notice this on a hand full of albums were none of the MP3s within the album will play. I just get the spinning play button and nothing happens (see screen shot) If I download the MP3s in question to my computer they play no problem. I have also checked file permissions and they appear to have the same permissions as all the other albums/songs that play without issue.
The log file /var/log/subsonic.log does not log any event when attempting to play one of these MP3s, so I don't have much to go on.
More info:
Subsonic 6 standalone version running on FreeBSD 10.1
screen shot of play button when it can't play song (it just spins and spins)

Any help would be greatly appreciated thanks!
