While it may not be known in the US, Deezer is a very popular music service that has amassed plenty of fans worldwide. The French company offers a huge catalogue of songs, over 40M to be accurate, which puts it ahead of Spotify, Google Play Music, and Apple Music, and includes international releases as well as local music from different parts of the world. Its real tour de force though: quasi-worldwide presence. Deezer has been available in more than 180 countries since 2013, but there was one missing in the list: the USA.
To be accurate, Deezer has been accessible in the US before, but only through Cricket Wireless or on Sonos and Bose speakers. Now, it should be available to everyone with a $10 monthly plan and a 30-day free trial.
If you live in the US, I'm not sure what the added value of Deezer is, beside the fact that your subscription will continue working almost regardless of the country you might travel or move to. Deezer is popular because it brings legal music subscriptions to countries where other options are either inexistent or mediocre, but in the US, you have Google Play Music with YouTube Red, Spotify, Apple Music, Tidal, and plenty of free internet radio services like Pandora. Competition is tough and the benefit of Deezer is harder to grasp in this landscape.
If you're interested though, you can give Deezer a try and see what it has in store for you. At the very least, you should get Android Auto and Chromecast support, but that is only if you manage to get through the first sign-in process. Artem has been trying it and he keeps getting this blank screen or the option to pay to upgrade. Whether this is happening because of a bug with the first rollout of the service in the US or because the US doesn't have the free plan that other countries do (I am a free user in Lebanon), I'm not sure.
