Music streaming platform Spotify filed a formal antitrust complaint against competitor Apple Inc., claiming the Cupertino, California-based company unfairly taxes services on its app store and blocks updates to consumers.

The complaint was filed Monday with the European Commission, as European Union regulators are scrutinizing large tech companies over antitrust concerns. Last July, the commission hit Google with a massive, record-setting $5 billion fine over alleged antitrust violations. Facebook faced restrictions from German antitrust authorities in February.
