I understand what you're saying but either they bought a license to use the song, or it was royalty-free. Just a coincidence that it was used for another game.
They probably didn't even realize this song was used in PC videos haha
It is very likely they bought a license to use the music for that promotion video. You can find and listen to the music at audionetwork.com: Tread Fast. (there's more music on that website that is used for Planet Coaster videos)
