YouTube row with Warner silences bands

Music videos from artists such as Madonna and Led Zeppelin have been removed from YouTube in a row over licensing.

Video from acts signed to Warner Music Group will no longer be available on the video sharing website after a contract dispute between the two firms.

Both are locked in a battle over licensing agreements for Warner's music videos and the fee that Google-owned YouTube pays the label when videos are watched.

Warner said: "We are working actively to find a resolution."
