"Bye Bye" served as the album's thirteenth track, and also composed by Carey and Stargate. An "inspirational power ballad", it is influenced by R&B and pop music genres. The song is built on an understated and simple piano-driven melody, that is decorated with a soft bass-line. Lyrically, the song was described by critics as a "larger than life anthem", and an "inspirational lighter-in-the-air ballad", and finds Carey remembering both her father, as well as any lost loved ones. While the verses are dedicated to him, the chorus was written in a third-person point of view, for her fans: "This is for my peoples who just lost somebody / Your best friend, your baby, your man or your lady / Put your hand way up high / We will never say bye / Mamas, daddies, sisters, brothers, friends and cousins / This is for my peoples who lost their grandmothers / Lift your hands to the sky / Because we won't ever say bye bye". While listing several forms of loss, Carey encourages to never let go, and always live with their memory, and put their hands up if they ever lost someone, 'cause we won't ever say bye bye'. Serving as the album's closing number, "I Wish You Well" was compared to the closing number on "Mimi", "Fly Like a Bird". Similarly, "I Wish You Well" incorporates gospel influence into its melody of "rousing piano waltz", that "extends forgiveness to those who have wronged her in the past and is pretty much interchangeable with its predecessors." Extensively making use of the whistle register, she references Mottola in another light than "Side Effects": "'I Wish You Well's' message to Mottola is similarly striking. Accompanied by a piano and some multi-tracked backing vocals, Carey sings: "Still bruised, still walk on eggshells / Same frightened child, hide to protect myself / But you can't manipulate me like before." She then prescribes Bible study and says, "I wish you well."
