Apple may want to queue up a good blues playlist on iTunes. In a report released today at the Web Summit in Dublin, music publisher Kobalt said that for the first time royalties collected by its European musicians from Spotify have eclipsed the royalties they received from iTunes. Kobalt reported that royalties from Spotify’s streaming service in the first three months of 2014 were 13% higher than those received from digital iTunes downloads. Just six months earlier, in Q3 2013, those artists received 32% more from iTunes. In Q4 2014, iTunes’ lead over Spotify had shrunk to 8%, according to Kobalt.
