I dont have to get into the exact wordings of the song.Guess you would have known which song we are talking about.
Half way through this song the tune changes, for no apparent reason. (This is not a song of reason- thats a different story.) But going by the audience response it could have be one of the factors for it being a sensational hit.
Sometimes we have to change our tune to stay on track. call it Tune Change or Strategy change or whatever. but the flexibility to change strategies mid way even if that meant eating humble pie.
