It has turned out that not everyone files a copyright notice for their published songs.
Strongly recommended, because even though we monitor streams and other network events like a hawk, at NCB they have power to monitor copyright compensation whenever your work is performed or when it is recorded on audio or AV recording.
So check the vibe, and make the necessary notes in that direction as well. You can do it online from the attached link (In FInland).
