Spotify has let it be known that it has something to show off to the world on April 24, and while the company itself is staying tight-lipped, the signs point towards some kind of speaker hardware being unveiled – maybe a 4G/LTE device that fits inside your car.

Back in February, some Spotify users were getting special offers relating to a compact in-car speaker with a data connection, as The Verge reports: apparently it would cost $12.99 or $14.99 all in. Spotify never followed up on these offers, but the device shown in the associated imagery had physical playback buttons and a green LED ring.
