Are Facebook getting set to launch their own music service?  There are a few clues suggesting that this may be the case. Computer nerds reckon they found evidence of the source codes for it in the coding for its Skype powered video chat service.

The music service is believed to be a partnership between the social networking service, Spotify, MOG and Rdio and is expected to be launched at Facebook’s annual f8 developer conference on September 22.

The annual conference is typically where Facebook announces new site features, such as last year’s launch of the ‘Like’ function for other websites.

Snouts familiar with the plans have revealed to www.mashable.com that Facebook won’t directly host or stream the music or other media. Rather, it will depend on music service partners to source and provide content, in direct contrast to other music services provided by Google, Apple and Amazon which host the content on their servers.

There are also suggestions that this new function will go beyond just music – whispers suggest that a movie streaming service may be on the way, with talk of a partnership with Netflix to stream movies.

However, the official word from Facebook is vague, with a spokesperson telling Mashable “There’s nothing new to announce. Many of the most popular music services around the world are integrated with Facebook and we’re constantly talking to our partners about ways to improve these integrations.”
