And when Brad Paisley joined in as a guest on "Freedom Was a Highway," Allen also got to live out the role of another fellow artist who was otherwise absent from the lineup. "I always wanted to be like a darker-complected Keith Urban, but I don't play the guitar that well," deadpans Allen. "And I'm a little taller." Artist Mentioned "Freedom" is indeed a little Urban-esque: It includes a bold guitar solo from Paisley and a key noodling banjo riff while celebrating the unfettered excitement of youth a la Urban's "Wasted Time." But "Freedom" is also a little bit Jackson Browne, with mentions of wheels and pavement symbolizing the same late-teens period referenced in "Running on Empty."
