with Smith more than Tom Petty himself, because he has a history of not really caring about this stuff. A few years ago people made allegations that the RHCP's "Dani California" was a copy of "Mary Jane's Last Dance" and Petty's quote was:

“I seriously doubt that there is any negative intent there. And a lot of rock ‘n’ roll songs sound alike. Ask Chuck Berry. The Strokes took ‘American Girl’ [for their song 'Last Nite'], and I saw an interview with them where they actually admitted it. That made me laugh out loud. I was like, ‘OK, good for you’ … If someone took my song note for note and stole it maliciously, then maybe [I'd sue]. But I don’t believe in lawsuits much. I think there are enough frivolous law suits in this country without people fighting over pop songs.”
