You've heard the story recently that classic rocker Tom Petty is upset with British pop star Sam Smith for allegedly lifting some similarities from his song "I Won't Back Down" for Sam's hit song "Stay With Me". Here's more proof.

Check out this YouTube clip that’s been making the rounds really drives that message home. User Envanligfjant originally posted this comparison clip last summer but has really gotten a lot of attention over the past few days.

By the way, this is what Tom Petty says about the whole thing on his website

"About the Sam Smith thing. Let me say I have never had any hard feelings toward Sam.  All my years of songwriting have shown me these things can happen.  Most times you catch it before it gets out the studio door but in this case it got by.  Sam’s people were very understanding of our predicament and we easily came to an agreement.  The word lawsuit was never even said and was never my intention.  And no more was to be said about it. How it got out to the press is beyond Sam or myself.  Sam did the right thing and I have thought no more about this.  A musical accident no more no less. In these times we live in this is hardly news. I wish Sam all the best for his ongoing career. Peace and love to all."

Listen to it, what do you think was it a 'musical accident'?
