Hello, I did search for an answer to this question, I have found many that answer the most part of it, but not all. I Recorded couple of song covers on the piano and I would like to monetize from them. I've got an e-mail from YouTube saying that I need to provide a proof of commercial use rights in order to monetize. Does this mean that I can tick the box and let YouTube review this again or would this be against the copyrights and law ? Thanks!
