The case is one of four opened by the EU competition enforcer into Apple in June last year. The EU charge sheet usually indicates whether a fine is merited and what companies have to do to halt anti-competitive practices.
The Commission declined to comment.
Apple was not immediately available to comment. It has said its App Store helped Spotify to benefit from hundreds of millions of app downloads to become Europe's largest music streaming service.
Spotify in its 2019 complaint to the Commission said Apple unfairly restricts rivals to its own music steaming service Apple Music and also protested against the 30 percent fee levied on app developers to use Apple's in-app purchase system (IAP).
