title should be Solnyshko (BLVCK CVRNVGE Remix), not sure if its either Remix or RMX due to the metadata source, but there should always be a space after initial song title if its edited (remixes, cuts etc)
Original source (https://soundcloud.com/blvckcvrnvge/demo_solnyshko-blvck-cvrnvge-rmx) has the Title "Солнышко (BLVCK CVRNVGE RMX)" so consider changing the Title:
Солнышко (BLVCK CVRNVGE remix) -> Солнышко (BLVCK CVRNVGE RMX)
Solnyshko (BLVCK CVRNVGE remix) -> Solnyshko (BLVCK CVRNVGE RMX)
