Amuse protects and monetizes your music on YouTube and collects payments that can be retrieved from the Amuse app as we do on other stores.
Here are your options for dealing with YouTube.
1. Amuse continues to collect money/monetize your YouTube channel and all other YouTube channels that uses your music. You can withdraw the payments from the Amuse app.
2. Amuse releases its claim on your music on your and all other channels using your music. Your music will no longer be monetised on YouTube at all. Amuse still collects revenue from all other music stores. You can do this in the app before release by not checking YouTube as one of the stores to deliver to or you can contact support after release.
3. Amuse releases its claim on your channel but continues to collect revenue from other YouTube channels that use your music.
In all of the cases you own the rights to the work 100%. Amuse is only ever acting as a collecting service in this regard.
