The Cover Versions actor previously told PEOPLE his favorite track off her latest album is the piano ballad “New Year’s Day.” Taylor Swift “I love how that song, like so many of hers, captures something very honest about the quiet but meaningful moments in a relationship,” Austin said. “A number of times I’ve gotten to hear Taylor’s songs at the stage where they’re just her and a piano.
