Spotify said Monday it would expand significantly to new markets over the next few days, a rollout that would expand its availability to more than a billion people around the world.

Spotify is currently available across about half of the world, “but there are still millions of creators and billions of listeners who don’t yet have access to Spotify,” CEO Daniel Ek said, adding that more details would be released shortly.

The news came out of Spotify‘s Stream On event, aimed to reveal how the streaming-music giant wants to improve both creator and fan experiences on its service. Monday’s two-hour virtual event was expected to release news both for listeners of Spotify and for audio creators using the service, likely including music artists and podcasters alike.

Spotify, the biggest streaming service by both listeners and subscribers, hasn’t held one of these events since 2018 when it overhauled its free mobile tier. It amped up what you could hear with a free account, unlocking on-demand songs that previously were available only to paying customers. Changes like those, and Spotify’s obession with expanding into podcasts of late, have vaulted the company to 345 million listeners and 155 million paying subscribers as of the end of last year.
