People say that MKW's Rainbow Road sounds like Good Egg Galaxy


King Bowser
Someone said it's between the 24th to 36th seconds of the song. I still don't notice any similarity, and I usually notice similarities with video game music.
The main theme is part of the background melody. It's kinda hard to hear.
Parts of the music were inspired by Super Mario Galaxy's "Good Egg Galaxy" music. Makes sense to me here.
And the other factor is that even though this "version" is different, some instrument elements almost SOUND like what you'd hear from the Mario Galaxy Orchestra, if I'm not mistaken.
