Did Sochi rip-off Log Horizon?
Both of them are probably ripoffs.
Shit this sounds familiar
Musical patterns like this aren't uncommon. I don't know enough about music to name the different terms, but let's just say people have been inventing the same wheel for centuries.
I for example thought I had heard some of the SnK OST in some random Dutch show, just turns out they're kinda similar.
Sawano probably does rip-off other music all the time.
