Sunnyvale, Calif. - Social.FM, a social music service for mobile and Web users that allows sharing of streaming music playlists, on Monday announced a partnership with mobile media distributor Handmark.

Sunnyvale, Calif. - Social music discovery service Social.FM announced on Wednesday the release of a Facebook application that automatically scans users' profiles and creates an online radio player featuring full-length tracks from their favorite artists.

Sunnyvale, Calif. - Online music service Mercora, which lets users create their own Internet radio stations, said on Wednesday that it has launched a new service and changed its corporate name to Social.FM.
