Local Files looks synced but wont play? (video Included)

[jacobst99]

I'm posting a Video where i try to play a local file that i've synced, but it won't play! All other local files plays easily on the phone, and this file also plays on the computer in mp3 format so it shouldn't be anything wrong. I don't have a clue what can be wrong? Also, im on a mac and does not have firewall enabled.

The songfile is white and should be able to play. But the song just does not play, at all, and switch song.
