Yandex Music (Яндекс Музыка) is a Russian music streaming service from Yandex, launched in 2010. It offers music, podcasts and DRM-protected music videos through apps for iOS, Android, Windows and macOS, and on the web. According to Wikipedia, it is offered in a limited set of countries, mainly Russia and neighbouring states, and subscriptions can only be paid for from those countries. The web page tells visitors from other regions that the service is not available there.
Yandex Music is a Russian product. Yandex N.V., the Dutch parent of the Yandex group, sold its remaining Russian stake to a Russian investor consortium in 2024. The website does not state where data is hosted. The software is not open source and cannot be self-hosted. For a European organisation, besides data protection, the questions are whether the service is available in its region and whether use fits applicable sanctions and internal policies.
