Spotify, the music startup that has taken the Internet by storm due in large part to its presence on Facebook, has some good news for those who use the ad-supported version of the service after saying it will continue to offer unlimited music.

We've been so overwhelmed by the U.S. response to Spotify that we've extended the honeymoon for unlimited free listening, the company wrote on its blog Thursday. Right now, if you're a free user, you can continue to enjoy millions and millions of tracks without time limits, gimmicks or catches. It's our way of saying thanks to the US!

Spotify would not say how long it plans on offering the ad-supported unlimited option.

Spotify has two other tiers of service.

The Unlimited tier removes the ads for $4.99 a month. Premium Spotify users get Spotify on their mobile device for $9.99 a month.

The service has a social component as everyone on Facebook knows by being able to see what your friends are listening to on Spotify via Facebook's news feed.

The service kicked off its American operation July 14th after first delving into the European market. Spotify had 10 million European users at the time of its U.S. launch.

The company has undoubtedly been successful in America since it originally planned to offer the free version of its service for only six months.
