Currently Spotify can be used as a desktop application or a mobile application. However the company is preparing to launch a web-browser version. This move would directly compete against Pandora and rumored upcoming browser-based version of iTunes. Spotify’s music streaming app lets people listen to an unlimited number of songs for free with ads. To sync their accounts with the mobile app and without ads, Spotify charges $10 per month. About 4 million people have the paid version of Spotify as of late July. The web browser version of Spotify would help improve music discovery.
