Spotify this morning invited press to an April 24th event in New York City, where the streaming music company says it will make “a news announcement.” Unfortunately, the invitation offers zero clues as to what the pending announcement could be.

Spotify has been testing voice controls for its app of late, so the news could be a wider rollout of that feature. And job listings continue to hint at the company’s potential hardware ambitions. But “news announcement” doesn’t exactly point to some grand product unveiling. Spotify could also make adjustments to its free and / or paid tiers as the company continues trying to fend off Apple Music and maintain its lead over rival music services.

The event will come after Spotify’s successful IPO earlier this week on the New York Stock Exchange.
