The music industry and You Tube are set to go head-to-head this week in a crucial vote in brussels that could force the digital giant to pay billions of dollars in fees to popular artists such as Taylor Swift Ed Sheeran and Katy Perry.For years the music industry has argued that You Tube exploits the lack of legal protection around music videos being viewed on its service to pay minimal amounts to artists and labels YouTube got a bloody nose in last months vote but its supporters are expected to gather the MEPs needed to challenge that decision and force a vote by all 751 members of the parliament Last month's vote was a fantastic result,but I'm sure there will be some push back.YouTube is the biggest music service,full stop,by some margin and has been a severe imbalance in what artists receive.It is righting a wrong really.said Martin Mills,founder of Beggars Group.Taylor Swift has led the fight for artists to get a better share of revenues in the age of the digital music giants.In 2014,she pulled her music from Spotify,saying artists receive a tiny royalty per song play and has been the catalyst for the much better deals struck by record labels with Spotify in the past 18 months“Despacito would probably not have become the global phenomenon it did without YouTube,”says Mark Mulligan,analyst at MIDiA Research.Last year,Luis Fonsi and daddy Yankee's reggaeton hit took the world by storm,becoming the most streamed song of all time You tube is the number one place where young people discover music.If you are going to create global hits you need You Tube and it is becoming more important to musicians."YouTube makes money from advertising and last year paid 856m（&650m）in royalties to music companies-an estimated 67 cents from each of its 1.3 billion music lovers annually.In the UK,record labels and artists earn more than double the royalties from the sale of 4.1m vinyl records than they did from the 25bn music videos watched on YouTube last year Musician Billy Bragg says the battle against You Tube is less about the potential financial windfall that artists might get,and more about making sure the new digital music power players play fair.We,ve all seen how,with the recent data protection legislation,the European Union has shifted power to the individual online,he says.u Now theyre seeking to do the same for artists.All were asking for is a level playing field.rebalancing the power between artists and the internet tech giants who are making massive profits while paying tiny royalties You Tube has made moves to mollify the industry,launching a premium subscription service-two days before the crucial European vote-a move Jean-Michel Jarre,electro-pioneer and president of music body Cisac,has cynically called"indirect lobbying"to try to improve its image
