Qloud, a music streaming service for social networks funded by Steve Case's Revolution, has cast its lot in with Google's OpenSocial initiative.

In a company release, Qloud termed its fast acceptance of the OpenSocial APIs "a fundamental step toward quickly and easily making the web more social."

The Qloud application enables users to share their music libraries — on iTunes, for example — with other users, mainly on social networks like Facebook.
