Spotify reached 83 million subscribers. Elizabeth Keatinge has more.

The battle for music-flowing titans is officially on.

On Wednesday, Spotify complained to the European Commission's antitrust regulator that Apple did not play fair and harm consumers. Spotify CEO Daniel Ek claimed that the App Store guidelines give Apple Music an "unfair advantage at every turn."

On Thursday, Apple hit back against the streaming service by saying Spotify wants "all the benefits of a free app without being free." The iPhone manufacturer also threw in a couple of more subtle jabs in the long "Addressing Spotify's Claims" press release.

Apple said in its public retort that Spotify has been using the App Store "for years to dramatically increase its business," but now it wants to reap benefits "without making any contribution to that marketplace."

"Most customers use their free, ad-supported product, which doesn't contribute to the App Store," Apple said. "Even now, only a small part of their subscription falls under Apple's revenue sharing model. Spotify requests that the number be zero."

In response to Spotify's claim to Apple blocked it out of services like Siri, HomePod and Apple Watch, Apple said it came out to Spotify "on several occasions," as Spotify said it's "working with."

The giant of technology added that Spotify's mention of Apple Watch was "particularly surprising" since the Spotify Watch app was reviewed and accepted back in 2018 with the same process and speed of any other app.

"The only thing The contribution Apple requires is for digital goods and services purchased in the app, using our secure app purchase system, "Apple's statement said.

About Apple's 30 percent tax on paid apps, located in the center of Spotify's complaint since Apple Music is not subject to it, Apple Spotify says its feelings are misleading.

"The revenue share is 30 percent for the first year of an annual subscription – but they ruled out falling to 15 percent over the years," Apple said.

"We feel a duty to respond when Spotify breaks its financial motivations into deceptive rhetoric about who we are," Apple said. "Spotify wouldn't be the business they are today without the App Store ecosystem."
