Eva Cassidy - Ain’t No Sunshine 

ain't no sunshine when he's gone
it's not warm when he's away
ain't no sunshine when he's gone
and he's always gone too long
anytime he goes away
wonder this time where he's gone
wonder if he's gone to stay
ain't no sunshine when he's gone
and this house just ain't no home
anytime he goes away
and i know, i know...
ain't no sunshine when he's gone
ain't no sunshine when he's gone
only darkness everyday
ain't no sunshine when he's gone
and this house just ain't no home
anytime he goes away
ain't no sunshine
ain't no sun ain't no sun
ain't no sunshine when he's gone
anytime he goes away
ain't no sun
he's always gone too long
