Apple has responded to a complaint by Spotify to the EU commission, stating it only collects a fee on less than one per cent of the music streaming platforms userbase.
Apple said in a filing Spotify pays a 15 per cent fee on about 680,000 of its 100m premium customers.
It follows a complaint by Spotify chief Daniel Ek in March which blasted Apple for levying a 30 per cent commission on in-app purchases taken out via its App Store. The fee drops to 15 per cent after one year.
Apple said none of Spotifys premium users currently pay the 30 per cent tier, as Spotify ceased collecting subscription payments through the App Store in 2016.
Spotifys complaint to regulators also included allegations beyond Apples fees, including steps that Spotify said Apple took after it quit using the App Stores payment mechanism.
The company pointed to tightened App Store rules after 2016 that bar developers from providing links or buttons to external web pages showing users how to pay for an upgrade to premium subscription outside the App Store.
However Spotify is not the only complainant against Apples App Store and alleged anti-competitive practices.
In May, the US Supreme Court ruled against Apple in a lawsuit brought by consumers which accused the firm of creating a monopoly via its commission charges.
