Tom Petty's 13th album doesn't hit shelves until later this month, but five songs have already been released and apparently RS readers are willing to bet the other six aren't complete turkeys. The whole thing is somewhat a throwback to Petty's earliest albums. "I knew I wanted to do a rock & roll record," he told Rolling Stone earlier this year. "We hadn't made a straight hard-rockin' record, from beginning to end, in a long time ... This band just grows and grows, and that's an incredible gift. I can't see us calling it off. They're still the guys I want to play with – and the guys who understand my songs the best."
