The popular social networking site has licensed technology that will help it prevent unauthorised copyrighted music from being posted to MySpace users' pages.

The 'audio fingerprinting' technology, offered from Gracenote, will allow MySpace to block certain music recordings from being posted, and therefore help fend off objections from content owners about the growing availability of protected content on its site. It uses Gracenote's MusicID audio fingerprinting technology and Global Media Database.

MySpace will review all music audio recordings uploaded by community members to their profiles, identifying copyrighted tracks, and blocking the uploading of such music as appropriate.
