Lines that Melt

Chega de Saudade - Antonio Carlos Jobim
Talking about alluringly charming line, this is classic Jobim. His line "Vai minha tristeza e diz a ela que sem ela nao pode ser..." (A poor translation: "Go my sadness! And tell her that without her I can't do") will melt most girls' hearts like marshmallows in a hot chocolate (Disclaimer: Unless the guy is a real prick).
