Not available in the US yet for copyright reasons but they're aiming for a US launch later in 2018. Their catalog stands at half a million titles and they just got Deutsche Grammophon on board. Subscription is currently 9.99 euros/month in Germany, as far as I can tell. (The website is limited when accessed from a US location.) Full disclosure, I actually went to school with one of the co-founders, although we were never close friends.
