I'm puzzled why every time I upload background music from PD 365's library to Youtube, Youtube flags the music track as a copyright violation and, when I dispute the copyright violation through Youtube's process, I usually lose the dispute. For example, below are the last three videos I've uploaded to Youtube with tracks from PD 365's music library.
Copyrighted content: Dramatic Battle Claimed by: Pirames International Srl
Copyrighted content: Borderline-5 Alarm Music - Sonic Quiver - Direct - Sonic Quiver
Copyrighted content: Fur Elise Claimed by: CD Baby
The only dispute that I prevailed in, above, was Borderline-5.
I'm puzzled as to what is going on.
