The once dominant MySpace has turned to the company that stole its crown, Facebook for help to drive users to its ailing site.
The two launched Mashup with Facebook, to let MySpace users log into their Facebook accounts through their MySpace page.
This means users can port over their likes and interests listed on Facebook.
In turn users will get a stream of entertainment content based on these preferences.
"We feel this is a complimentary service to Facebook," said Mike Jones, MySpace chief executive officer.
"This new feature is a great illustration of our strategy around social entertainment and enabling the real-time stream".
MySpace is among more than a million websites letting Facebook members extend their social graph on the world's biggest social network to other parts of the web.
Facebook's vice president of partnerships Dan Rose said the sharing of information is a strategy that "makes a lot of sense".
"Sharing entertainment and music interests is part of many of our friendships, online and off.
"MySpace is giving people an easy way to bring their favourite bands, celebrities and movies from Facebook to create a personalised experience on MySpace from the start," added Mr Rose.
