An artist, track, or album is no longer available
All music on the service is hosted in accordance with license agreements with the copyright holders. If you are not able to find an artist, track, or album that was previously available, it probably means that their agreement with Yandex.Music has ended.
We are invested in expanding our music catalog and try to sign contracts with as many copyright holders as possible.
It's also possible that music was deleted because a copyright holder complained.
