The updated site is meant to be a centralized location that will let artists access the Apple Music tools and services that are available to them. Artists.Apple.com will serve as the home for all artist activity on Apple Music, and it will act as an entry point into what the Apple ecosystem has to offer.
There are tools for creating Apple Music-branded marketing assets, earning money through the Apple Music Affiliate Program, and accessing Apple Music analytics. Apple has also added walkthroughs and support document help for new features, such as Spatial Audio.
Apple Music for Artists is available for every artist on Apple Music, offering up stream data, Shazam info, sales numbers, and all of the new features introduced today. New content and resources for artists will be added to the site over time.
