Stockholm-based Spotify, which sparked speculation related to an IPO after it re-advertised a job for a regulatory filings expert in August, provides free on-demand music or ad-free tunes for paying customers.
The company said in November its paying subscriber base had risen to 12.5 million from 10 million in May.
Rival Pandora Media Inc said in October it had 76.5 million active listeners as of September 30.
Spotify in its blog post on Monday said:
We had an amazing 2014 at Spotify and owe it all to you, the music fans who listen, discover, share and celebrate music and artists with us every day of the year.
And before 2014 turned into 2015, we reached 15 million subscribers and 60 million active users!
So as we set off into the new year, we want to send a giant thank you to all of you. We can't wait for the year in music ahead!
