A wave of antitrust interest is washing over Europe and much of the United States, and Spotify is riding its crest.

The Swedish audio-streaming giant lodged a complaint against Apple with the European Commission on Wednesday, accusing the company of abusing its position as owner of the App Store to stifle competition. Specifically, Spotify says that by charging a 30 percent tax on in-app purchases, Apple forces app developers to make an impossible choice: Either pass those costs on to consumers, or refuse to pay the commission and face a litany of technical hurdles imposed by Apple. Spotify, which competes directly with Apple Music, argues that this constitutes an unfair advantage for Apple.
