Streaming service Deezer has launched in Turkey, after a pre-launch process that hit the odd licensing bump. Deezer’s full service is now live in Turkey with its full catalogue of international and local music. Key to the launch were licensing deals with collecting societies MSG and MESAM. “We are confident that Deezer will dearly value the catalogue that MSG represents and will pay all royalties,” said MSG board chairman Garo Mafyan, in a quote that presumably isn’t intended to sound quite as menacing as it does. There may be some licensing stories to tell though: “We have been working towards launching in the Turkish market for the past nine months,” said Deezer’s general manager for Turkey Selen Zorlu. As we reported in July, Deezer had been subject to an “access detainment action” (i.e. a ban) in Turkey for a few days as it negotiated licensing deals, at a time when it was running a “minimum trial service” there. The launch reinforces Turkey’s status as a fascinating digital-music market, with MÜ-YAP continuing to be one of the world’s most popular YouTube channels.
