Facebook will launch a music service on September 22nd, CNBC reported today. There are currently no details on whether it will be a streaming subscription service or simply a music storefront similar to iTunes, and Facebook has not yet confirmed the announcement. Business Insider said the Facebook music service will integrate with other third party services such as Spotify and Rdio. CNBC also suggested Facebook will work with MOG, another music service that has a long-standing relationship with Facebook. Spotify and Rdio currently allow users to integrate with social networks to share songs and playlists with friends.
