MySpace who have come under fire as “copyright infringers” will use “audio fingerprinting” technology to block users from uploading copyright music to the social networking site.

“MySpace is staunchly committed to protecting artists’ rights, whether those artists are on major labels or are independent acts,” said Chris DeWolfe, MySpace chief executive and co-founder.

The company said users who repeatedly attempt to upload copyright music files will be permanently barred from the site.

Online sites such as MySpace and YouTube have come under fire from major record labels who have sued in some cases to prevent copyright music from being included as the soundtrack to a user-generated content.
