Spotify is adding new markets, including Germany, and features such as incorporating the service on Facebook Inc. and other social networks to build subscribers. The company released an application for Apple Inc.'s iPad in May and one for Google Inc.'s Android operating system last month.

The London-based service has 15 million users of the ad-supported music service, which is limited to playback on computers. Spotify has 4 million subscribers paying $4.99 a month for ad-free access on desktops and laptops or $9.99 including mobile devices.

Spotify has deals with Sony Corp. 's Sony Music, Vivendi SA's Universal Music, EMI Group and Warner Music Group. Under those agreements, artists, record companies and publishers receive a cut of ad sales and subscriber fees.

The company faces competition from other subscription services, including Rdio Inc., as well as online ventures by Viacom Inc.'s MTV, AOL Inc. and Yahoo! Inc.
