Stefan Blom, Spotify's chief content officer, announced his departure via an internal memo today.
News of Blom's exit comes a month after we learned that Kevin Brown, the most senior industry-facing exec at Spotify outside the United States, was leaving the company.
A replacement for Blom - who has been with Spotify since 2014 - has not yet been named. The Apple Music service counts 30 million subscribers as of September, but its launch in June 2015 did not significantly impact Spotify as had been anticipated.
Via Twitter, Spotify also let the world know, this week, that it had surpassed 70 million subscribers.
Spotify charges its premium users a flat, $10 monthly fee for music streaming, the same as other major services like Apple Music, Tidal and Deezer. Worldwide, the app is now used by hundreds of millions of consumers, per Apple's estimate.
Last year, Spotify was valued at around $19 billion and has started 2018 with a confidential filing with a confidential filing with the U.S. Securities and Exchange Commission (SEC) for an IPO.
Spotify's valuation as of December topped US$19 billion (AU$27 billion), up from US$16 billion (AU$22 billion) earlier in the USA autumn, Reuters reported last month.
