Hey, who knows what nightcore is? ITS SOOO GOOD!!! Sorry, so nightcore is a version of music, sung in an anime way, aka higher and faster. Has anyone seen Anna Graceman's Treble Heart? If not, go look it up. The video up ^ is the nightcore version. Also, every time I write, I listen to a playlist of nightcore by one youtuber called NighcoreGalaxy Backup. She/He is super awesome!!
