False copyright claim on my youtube video.
I made a playthrough of the walking dead season 1. (unfinished). Recently; Sony Music Entertainment (Japan) Inc. Placed a Copyright claim on my video for the audio track: "ポルノグラフィティ-Winding Road(short ver.)" Which is not even in the video The video is unpopular, and only has six views. The claim states the track plays at 56:01. My entire video, with my commentary, is completely muted. Here is a link to the video. What do I do? I mostly make the videos for family viewing.
