Sam Smith’s ‘Stay With Me’ Sounds Similar to Old Tom Petty Hit ‘Won’t Back Down,’ Lawyers Agree [Video]

With only so many musical notes and chords available, and the competition to produce hit records at an all time high, it's inevitable that a lot of songs begin to sound the same.

And while it's not as telling as this video of country hits being mashed together, Sam Smith's current smash "Stay With Me" is pretty close to Tom Petty's "Won't Back Down".

Tom's co-writer on "Won't Back Down", Jeff Lynne of ELO fame, thought the songs sounded a little too close together, so he advised his lawyers. Now Sam pays some of his royalties to Tom and Jeff.

Funny how that all works out.

Here's the two songs being played on top of each other. Perfect match.

Here's a guy who tells you how to match them up.

And then there's this mash up done by a beautiful woman.

Now if someone could explain to me why the Red Hot Chili Peppers "Dani California" sounds like Tom Petty's "Last Dance With Mary Jane"
