Universal Music Group has agreed to pay royalties to independent artists whose videos are streamed on Vevo, the fast-growing music-video platform the label co-owns with Sony Music Entertainment and Abu Dhabi Media, reports PaidContent. The deal, brokered by the National Music Publishers Association, allows indie songwriters and music publishers to collect royalties from Vevo for the first time. Vevo took in $150 million in revenue last year, mostly from ad sales in 2011.
