Warner Music Group has ordered YouTube to remove all music videos by its artists after contract renegotiations broke down, reports Reuters.
The move, that will affect hundreds of thousands of video clips, is said to be due to Warner demanding more revenue from YouTube.
YouTube pays music companies a share of the advertising revenue from the site's video playback, with a per-play fee costing a fraction of penny, but because of volume it was thought to add up to a substantial amount.
"We simply cannot accept terms that fail to appropriately and fairly compensate recording artists, songwriters, labels and publishers for the value they provide", Warner said in a statement.
Reuters quotes a source "familiar with Warner Music's talks" that said the amounts it has been receiving from YouTube were "staggeringly low".
