I always thought “Mad World” had a very similar melodic theme to a classic by Bobby Vinton. It’s even in the same key! So I did a little mixing of the two to show the similarity. Coincidence? “Mad world” starts out as usual, then the mix kicks in around :18, then switches back again a but later. 
hummmmmm, I did not know that.
I going to call my mommy. She saw that movie.
Can you find similar tunes in MJ’s music?
MJ got sued for that a couple times.
