conversations.value: Write me a song called All I Want for Christmas Is You (SuperFestive!) with the following description: All I want For Christmas Is You, is a song written by Mariah Carey which has always been a huge Christmas #1
  However in this case, it is not on one of Mariah’s albums but Justin Bieber’s Christmas album, titled “Under The Mistletoe”
  Bieber features half way through the song and accompanies Mariah in singing the chorus. Make sure the lyrics are different from the original song.

  I just can't wait, yeah
  [Verse 1: Mariah Carey]
  I don't want a lot for Christmas
  There is just one thing I need (And I)
  Don't care about the presents
  Underneath the Christmas tree
  I don't need to hang my stockin'
  There upon the fireplace
  Santa Claus won't make me happy
  With a toy on Christmas Day
  [Chorus: Mariah Carey]
  I just want you for my own
  More than you could ever know
  Make my wish come true
  All I want for Christmas is you
  You, baby
  [Verse 2: Justin Bieber]
  Oh, I won't ask for much this Christmas
  I won't even wish for snow (And I)
  I'm just gonna keep on waitin'
  Underneath the mistletoe
  I won't make a list and send it
  To the North Pole for Saint Nick
  I won't even stay awake
  To hear those magic reindeer click [Chorus: Justin Bieber]
  'Cause I just want you here tonight
  Holdin' on to me so tight
  What more can I do?
  'Cause, baby, all I want for Christmas is you
  You, baby
  [Bridge: Justin Bieber & Mariah Carey, 
  Mariah Carey
  ]
  Oh-ho, all the lights are shining
  So brightly everywhere (So brightly, baby)
  And the sound of children laughter fills the air
  And everyone is singing
  , I hear those sleigh bells ringing
  Santa, won't you bring me the one I really need?
  Won't you please bring my baby to me? Yeah
  [Chorus: Mariah Carey, 
  Justin Bieber
  , 
  Both
  ]
  Oh, I don't want a lot for Christmas
  This is all I'm asking for
  I just wanna see my baby  (
  Yeah
  )
  Standin' right outside my door
  Oh, I just want you for my own (
  For my own, baby
  )
  More than you could ever know (
  Oh, no
  )
  Make my wish come true (
  Come true
  )
  Baby, 
  all I want for Christmas is you, baby
  [Outro: Justin Bieber & Mariah Carey]
  It's all I want for Christmas, baby
  All I want for Christmas is you
  It's all I want for Christmas
  All I want for Christmas is you
  It's all I want baby, yeah yeah
  All I want for Christmas is you, baby
  Whoa, whoa, whoa, whoa, whoa, ooh baby
  All I want for Christmas is you, baby
  All I really want is, want is, baby
  All I want for Christmas is you, baby
  All I want for Christmas is you, baby
  All I want for Christmas is you, baby
  All I want for Christmas is you, baby
