Really Don't Care (Demi Lovato) | Sounds Like | I Love It (Icona Pop)

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 [...]."
