Why oh why do they mess up..to me..some might just love it..the rhythm of a song.

Beautiful song, beautiful voice, wonderful orchestra in the background. I would not listen to it again for that reason. I really hate it when they do it..is it to be cute? Creative? Show that they are not bound to rhythm like people have been for millions of years of evolution?

Do others like it when this is done? mg
