The more i listen to Tom Petty’s songs both in heartbreakers and in his solo career, and now, with my recently...eh...achieved Travelling Wilburys collection, the more i’m convinced that his main source of inspiration it’s him, not John Lennon. I mean, assuming that Per said JL is a greater source of inspiration than McCartney, I tend to disagree now. not only the arrangements, but the basic musical ideas of the music and lyrics are so damn similar.
