Well, there is not much to do about it. Youtube or some countrys blocks videos on Youtube because of copyright issues. Either the song you have used or the movie/drama is being copyrighted. Almost all of my videos are getting matched third party or gets blocked in some country...Or the audio is removed..So things like this happens.. However there is only one help..even though it doesn't always help but you can try...
If you are using sony vegas, then try to pitch shift the song by 1 point or something. The song either gets deeper or softer..based on your likes..
