This song is one of the beautiful creations of Bappi Lahiri sahab, from the film, Zakhmee. Sung beautifully by great Lata ji, the song takes you to the unexplored world of dreams and fantasies, where there is only joy and no pain. Personally I like the melody of "AAO TUMHE" and the way it blends with "JINGLE BELLS", the famous rhyme.The song has been played in Hohner Chromonica 270 in the key of D#
