Reuters reports the company has signed up more than 250,000 paying customers here since its launch. The company revealed last month that its worldwide paying customer base has topped 2 million.
Spotify has not commented on the numbers.
The growth can partially be attributed to the pend up demand for Spotify in recent years. The company built a sterling reputation in Europe, which had US audiences craving it, so an initial burst of registrations wasn't surprising.
Things went into overdrive, though, when Facebook brought the company on stage at its f8 conference this year to showcase its new app structure that will allow users to share content. That put Spotify front and center among the social network's 800 million users. Today, the service is being used by almost 7 million Facebook users.
Launched in 2006, Spotify offers both a free as-supported service as well as the ad-free premium service, which can also be used on mobile devices. The service has a catalog of roughly 13 million songs, adding as many as 10,000 per day.
