I Have Played Guitar For over 5 years... i am 14 years old, i have always known the song ”Mary Janes Last Dance”, but I have only Recently learned the song ”Dani California”. True: the Chord Progression is Similar, but not the same. It is clear that this is NOT an act of Plagiarism, the Red Hot Chille Peppers Totally Wrote this Themselves, and this is definately an original Song... Besides Tom Petty is, like, a billion years old anyway, so his copyright laws are more likely than not, expired by now. LOL
