10. "I Won’t Back Down"
"That song frightened me when I wrote it," said Petty. "There's not a hint of metaphor in this thing. It's just blatantly straightforward." "I Won't Back Down" was written in the studio while "Free Fallin'" was being mixed. George Harrison, who performed background harmonies, told Petty that a line about "standing on the edge of the world" was dumb – so he promptly replaced it with "there ain't no easy way out." "I had a lot of second thoughts about recording that song," said Petty. "But everyone around me liked the song, and it turns out everyone was right."
