I don't know how many One Piece fans are here, but i found this cool connection

In 'Royalty,' there's a recurring sound effect throughout the song that sounds really similar to a sound effect from One Piece. In One Piece, this sound effect is very distinctly associated with a character who is dubbed the 'King of the Pirates' and has an ability known as 'Conquerer's Haki' – terms closely associated with 'Royalty'

Here's a link to the sound effect from One Piece: https://www.youtube.com/watch?v=BCLULjxI5Bg

I don't know if I'm reading too much into the song production, but it's a cool easter egg, if true. Do you guys hear it too?
