Usually YouTube straight up blocks the video if it detects copyrighted music. I have had it happen a couple times. I even had a video after about a year get approved out of the blue by the record label and it was unblocked again ( http://www.youtube.com/watch?v=ruEqBfvR4TE) and then even went on to be featured by YouTube … go figure….
I am not sure what your issue it – I can still play and hear it just fine.
