We're reaching out to artists and music copyright holders on behalf of AdRev. We protect and monetize music in YouTube through their Content ID system by creating audio fingerprints of your music, and then scanning all videos for any unauthorized uses of your content. When we find a match, we monetize the video, and the revenue generated gets paid down to you. We do not charge a set up fee, and we pay you 80% of the revenue generated, so there are never any out of pocket costs.
