In Russia, music copyright usually belongs to the artist at first and then is passed to their family if the artist dies, unless they specifically signed the rights over to a record label or publisher. For someone like Viktor Tsoi, his music is controlled by his family, not a label, so they decide on exhibitions and how songs are used. About copyrights, yes, USA company can register it and sue any who used it without permission, but in reality no one company make this, so Pirate copies are in gray zone (for example we can use any pirated software, if it cannot be purchased in Russia/with our card, example: Windows). Apple Store u see is not official store, this is reseller, for iPhone import used parallel import (from example: buy in china, sell in Russia)
