WASHINGTON » Spotify, a digital music service already popular in Europe, is now available in the United States.

Spotify lets users listen to songs on computers and mobile devices. It offers access to more than 15 million songs and gives users the ability to add digital music files that they already own.

The Swedish company is launching its service in the U.S. on Thursday. People can request invites to join on its website.

Spotify is offering a free, ad-supported version, as well as two subscription plans that do not include ads. A $4.99-a-month plan lets users access music on their computers and $9.99-a-month plan includes access on cellphones and other mobile devices, too.

Spotify currently has more than 10 million registered users and more than 1.6 million paying subscribers.
