Headlines and Titles of Works

Q. I am writing a novel. How do I write a title of a song in the body of the work (caps, bold, underline, italics, etc.)? Example: The Zombies’ “She’s Not There” looped in his head.

A. Noooo! Now that song is looping in my head (“but it’s too late to say you’re sorry . . .”). Use quotation marks. Thanks a lot.
