I have alot of Italian MLP dubbed music. I wanted to know if it was okay to upload them. Some are over a minute long,if that matters.

Do not upload significant portions of official content that hasn’t been freely released (promotional material etc. counts as freely released), such as a full page of a comic/book, more than 30 seconds of official video, or more than 10 seconds of official audio or copyrighted music. This applies to single uploads and to splitting contiguous portions across uploads.

Is it considered “freely released” if there’s a song up for public viewing on YouTube in it’s entirety from the actual copyright holders? I have found a high quality version of a music video using a song put up on public youtube with original pony animation over it. The original video was copyright blocked,and the reuploads on YouTube look like ass.
