Yandex Music has signed a deal with Facebook. Yandex Music is one of the most popular music streaming services in Russia. The deal means that Facebook users will now be able to share links to tracks from Yandex Music directly on the social network. Users' Facebook friends can listen to 30 seconds of music from these links directly on Facebook, with the full tracks being available on Yandex Music. Yandex Music has 20 million users in Russia, of whom a quarter of a million are paying subscribers. The deal will hopefully be beneficial for both companies, who share a main rival in Russia in the form of VK.
