"Fly" was recorded in New York City and was produced by Todd Clark.
MUSICInsideU says that "Fly is about the battle between who people think he is and tie him down to, and who he really is. "These people never notice me. Am I the only one who thinks it's hard." Phillip breaks other people's categories of him, mixing rock guitar solos with his typical acoustic sound. His almost-country style voice also blends with darker rock lyrics in the new single Fly." He added "The meaning of Phillip Phillips' Fly is about who he is - applied to you, it's about who you are. Outside, there's "the busy street... these people never notice me." I don't fit in, says Phillip, "it's hard to say what's on my mind." The questions are "give up? How should I survive?" A part feels like just giving in and blending into the "two thousand faces" of the crowd. The deeper part of Phillip rebels against just being like everyone else. "Think your fight is over? It's only so much closer." Phillip won't give up breaking out of the walls of this "cruel maze" of a nameless society: "I reach my hands to the sky... and fly!""
A fly on clothing is a covering over an opening concealing the mechanism, such as a zip, velcro, or buttons, used to close the opening. The term is most frequently applied to a short opening over the groin in trousers, shorts, and other garments, which makes them easier to put on or take off and allows men and boys to urinate without lowering the garment. The term is also used of overcoats, where a design of the same shape is used to hide a row of buttons. This style is common on a wide range of coats, from single-breasted Chesterfields to covert coats.
Trousers have varied historically in whether or not they have flies. Originally, trousers did not have flies or other openings, being pulled down for sanitary functions. The use of a codpiece, a separate covering attached to the trousers, became popular in 16th-century Europe, eventually evolving into an attached fall-front (or broad fall). The fly-front (split fall) emerged later. The panelled front returned as a sporting option, such as in riding breeches, but is now hardly used, flies being by far the most common fastening. Most flies now use a zip, though button flies continue in use.
