Spotify founder Daniel Ek has claimed that his platform has paid out more than $500m (£311) in music royalties since launching in 2008.
The news came as the company CEO revealed in a press conference in New York that Spotify can now boast of more than 5 million paying subscribers globally, with over 20 million active users in total.
Ek's royalties claim comes just a week after music video streaming platform VEVO said it had paid back more than $200m to the music industry since its launch in 2009.
The 5 million paying subscribers include more than a million in the US, according to The Guardian.
Said Ek: "We're the biggest subscription music service in the US, but also the fastest growing one. We've accomplished in one year what it took others a decade to do.
He added: "Spotify pays back nearly 70% of all the money that we get in to rights holders. We've now paid out more than half a billion dollars, and that's doubled in the last nine months."
Ek also confirmed that Metallica's music would be available on Spotify from next Thursday.
