I don't know if I've ever seen this in books I've read. From a copyright infringement standpoint what are the rules here? Is flat out copying a verse infringement? Even if you mention in your story who the author of the song is? What about if you split up the lines of the song into single quotes (as if the character was singing it outloud, and then after every line there would be come kind of commentary). For example... "line one from song" He sang loudly as he beat his hands to the music. "line two from song" He pushed his foot on the gas pedal even more as he sung along. Blah blah blah I'm just kind of curious as to what the rules are.
