songs with problematic playback cause glitchy playback behavior

1. import this song into library: http://superjoe.s3.amazonaws.com/temp/01%20Rooftops%20(A%20Liberation%20Broadcast).m4p
2. queue it up 10 times
3. queue up a good song after
4. play the first of the 10
5. it should skip all 10 songs because they cannot be played and start playing the good song. Instead, it stops playing altogether.
