 The seventh track on the album comes in the form of another medley , this time called " Here Comes Santa Claus ( Right Down Santa Claus Lane ) " / " <unk> Celebration " . Guerra noted that Carey adds some " club bounce " to " Here Comes Santa Claus ( Right Down Santa Claus Lane ) " , while Eric Henderson of Slant Magazine thought that the " <unk> Celebration " part of the medley " recycles the monolithic beat from Kurtis Blow ’ s instructive " Christmas Rappin ' . " " Charlie Brown Christmas " is a variation of the A Charlie Brown Christmas animated musical television special . A piece of nostalgia , as described by Guerra , it also makes use of traditional religious carols . A fourth medley titled " O Come All Ye Faithful " / " Hallelujah Chorus " features Carey 's mother , Patricia , who performs opera during the " Hallelujah Chorus " section . According to Bill Lamb of About.com , " Here Mariah Carey is at her best as she threatens to take everything too far sonically with operatic tones , impossibly high notes , and melisma in full force , but somehow it all holds together in exhilarating fashion .
