Warner Music Group has not been able to finalise negotiations with YouTube so they have pulled all their music from the site. There has been a lot of reports recently that YouTube will be a major revenue stream for all 4 major labels in 2009, but obviously Warner couldnt get the ad revenues they were after.

“We are working actively to find a resolution with YouTube that would enable the return of our artists’ content to the site,” Warner said in a statement. “Until then, we simply cannot accept terms that fail to appropriately and fairly compensate recording artists, songwriters, labels and publishers for the value they provide.”

Other sites have reported about Warner Music and YouTube non-deal, Thenextweb, Silicon Alley Insider and PaidContent.
