I think this song must be a classical one.But I can't remmeber what it is.It just sounds familiar to me.Have you heard it.I am sure many people have ever heard it. Here are part of the words from the song: Shining,shimmering,spledid Tell me,princess,now when did You last let you heart decide? I can open your eyes take you wonder by wonder Over,sideways and under On a magic carpet ride A whole new world A new fantastic point of view No one to tell us no Or where to go Or say we're only dreaming A whole new world A dazzling place I never knew But, now ,from way up here It's crystal clear
