Social media network Imeem claims the exclusive launch of actress Scarlett Johansson's debut album this week.

Johansson is the latest artist to debut her music on Imeem in the past month. The third-largest social network in the United States also boasts recent launches of music from The Rolling Stones, Avril Lavigne, and Ray.

The site offered free streaming of Johansson's Anywhere I Lay My Head on the star's Imeem profile a week before its general release in North America, scheduled for May 20. The page offers downloads, preorders for the album, music videos, and photos.

Users can add the music to their playlists and place Johansson among their favorite artists. Embeddable audio and video widgets allow users to share the music with friends and put in on their blogs, Web sites, and social networking profiles.

The site boasts 1 million songs and videos available through its library. It also allows users to upload their own music, videos, photos, slideshows, and blogs. It partners with all four major music labels and thousands of independent labels and video companies to offer ad-supported music and video. It launched in March 2006 and draws more than 24 million unique visitors a month.

Johansson's album is a compilation of singer and actor Tom Waits' material from several albums, including Bone Machine and Alice. It also contains one original composition called "Song for Jo." The album has received positive reviews, which indicate that it was heavily produced in an offbeat way to work with the actor's unusual singing voice.
