Amuse protects and monetizes your music on YouTube! This means that you will collect payment from everyone using your music (if it has Content ID) in their videos.
When music is detected in a YouTube-video with another owner, this is the message that they will receive.
As you can see, it is very clear that it is NOT a copyright strike. As the Content ID to your music belongs to Amuse, you will get this message when uploading your own music as well. But there is nothing we can do about that. Just remain sure that the music is yours as well as the money. Payments from Youtube is withdrawn from the app, same as other stores.
We cannot guarantee that Content ID will be provided to your music as YouTube has specific criteria as to what content can have Content ID ("must own exclusive rights to a substantial body of original material").
