If a remixer is credited on 80% of the assets in your product, then they are automatically listed as a primary artist on the release.
As a result, the release will appear on the Latest Releases section on the remixer's artist page.
It is important to note that if you have three primary artists on a product and a remixer is credited on 80% of the assets, then the remixer will be considered a primary artist, resulting in your release to be credited as Various Artists.
