Deezer, which has about 6 million subscribers worldwide, already has some users in the US, where it has been available only to AT&T's Cricket Wireless customers or on Sonos and Bose speaker systems.

The 9-year-old service will be available for $10 a month to all US consumers after 30-day free trials.

Catching up with competitors offering virtually the same product—unlimited access to tens of millions of songs could be challenging. Spotify, which launched a year after Deezer, counts more than 30 million paying subscribers worldwide and 70 million free users.

The playing field is crowded at the moment, with Apple's year-old Apple Music has 15 million paying subscribers, while Jay-Zs' Tidal has 4.2 million subscribers.
