Unfaithful (song) "Unfaithful" is a song by Barbadian singer Rihanna from her second studio album "A Girl like Me" (2006). It was written by Shaffer "Ne-Yo" Smith with the song's producers StarGate. The song was released by Def Jam Recordings on May 2, 2006, as the second single from the album. "Unfaithful" is a pop and R&B ballad and was inspired by the works of American rock band Evanescence. Originally titled "Murderer", the single speaks about a woman who regrets cheating on her partner.
C'Mon (Kesha song) "C'Mon" is a song by American singer Kesha from her second studio album, "Warrior" (2012). It was released as the album's second single on November 16, 2012, the same day of being released as a promotional single. The song was written by Kesha, Dr. Luke, Benny Blanco, Max Martin, Cirkut, and fellow pop singer and longtime collaborator Bonnie McKee, while production was handled by Dr. Luke, Blanco, and Cirkut. Containing elements of pop rap, "C'Mon" is a technopop song with brash lyrics that center on partying and falling in love. Stylistically, the song follows a verse–chorus pattern typical in pop music, with Kesha adding traditional singing in the latter and the discordant enunciation and stresses of vowels to force assonance and rhyme that epitomize her rap technique in the former.
