The verse vocal melody to Selena Gomez's The Heart Wants What it Wants (released November 6, 2014) is reminiscent of Jeannie (released 1967), the instrumental theme song to Screen Gems hit TV series "I Dream of Jeannie," which starred Barbara Eden and Larry Hagman. Compare the dotted eighth note rhythm of Selena's vocal lines: "[...] something I can't compare to/Nothing I've ev-er known I'm," with the jazzy dotted quarter note melody of Jeannie.

Demi Lovato's Dance-Pop single Really Don't Care (released May 20, 2014) seems closely modeled after Swedish duo Icona Pop's breakthrough hit I Love It (released May 9, 2012). Similarities include: verse vocal melody/rhythm (RDC starts on a G note, ILI starts on an Ab--only a half-step apart), theme (defiance to a former lover), lyrics ("I don't care" VS "I really don't care," "stars and moon collide" VS "down on earth, but I am up in space"), and production elements (drum beat/synth). Both song's verse vocal melodies start on the "and" or second eighth note of the first beat, and stay on the same note--emphasizing the upbeat--for the rest of the measure and most of the following measure. The final four notes of both melodies have the same exact rhythm (RDC: "[...] have it a-all"; ILI: "[..] you were g-one"). Finally, the pre-chorus vocal melody of Really Don't Care (which starts with the line "But even if the stars and moon collide") is tonally/rhythmically similar to the intro/chorus vocal melody to Pat Benatar's 80s smash Shadows of the Night (released September 30, 1982) i.e. "We're running with the shadows of the night [...]."
