Tom Petty says the reception The Heartbreakers have gotten for deeper cuts at their residencies in New York and Los Angeles could open up their set lists in the future.

Petty tells Rolling Stone, "I think that this could influence things quite a lot. It's just kind of a verification that the audience not only goes along with it, they like it... When I go to see people, I always kind of hope they are going to play some kind of songs I know... You're obligated to play some of that stuff that people know, but I don't think that's all you have to do. I think there's a way to fill everyone's needs. So who knows? This may have a tremendous effect on us from here out."
