"Reasons" is a lover's list, a man telling his partner exactly why she is everything to him. Earth Wind & Fire recorded it in 1975 as a slow-burning ballad built around Philip Bailey's falsetto, a vocal performance that sounds like it is coming from a different register of existence. The song does not argue. It catalogues. She is the reason for every good thing in his life. The list is the proof. Bailey's voice floats above the arrangement like the reasons themselves are too light to stay on the ground.
