the guy who posts all of this is “saigonstar” and its just the same melody but with different chords under like 20 songs or something.
theres only like a handful of songs that actually have legit melody
maybe they’re a modern pop artist… a lot of newer music seems to be the same thing over and over as well… lol. 
i swear almost every song is in C major and starts with some variation with the notes G, E, G, E, C and the melody doesnt match with the yt a
