There’s something almost incestuous about the way song titles are reduced, reused and recycled. When Lupe Fiasco sings about a rapper who is coping with his newly acquired fame and The Carpenters sing about a groupie who falls in unrequited love with a musician, and both of these tunes are called “Superstar,” it throws you off kilter. And yet, “Superstar” as a song title is far from the most hackneyed option. The corresponding Wikipedia page lists over 200 songs entitled “Hold On” featuring a sundry of artists, from the Jonas Brothers to Alabama Shakes to The Beekeepers. “Changes,” “Beautiful,” “Breathe” and — of course — “Love” are used just as often.
