Which tool is only available to music partners who have access to Content ID?

The Content Manager CMS (Content Management System) is a specialized tool exclusively available to music partners who have Content ID access. It provides advanced features for managing large catalogs of content, setting up Content ID policies, reviewing claims, and analyzing performance data. YouTube Studio is a general platform for all creators to manage their channels and videos. Analytics for Artists is a reporting tool for artists to understand their audience and performance, not a content management system. The Audio Library offers free music and sound effects for creators to use in their videos, but it's not for managing rights or Content ID.
