There has always been something sexy about hearing Fiona Apple sing "I've been a bad, bad girl" on her hit track "Criminal." It launched her entire career and developed her image as the naughtiest girl in rock. Her latest single "Every Single Night" was critically acclaimed as one of the best songs of the year, and while she frequently goes on hiatus from music, her return is always met with a warm welcome.
