Exalando comes from the verb exalar, meaning to exhale or to emanate. While it literally means to breathe out, it's often used metaphorically to describe something giving off a strong scent or feeling.

"Meu Beijo" is a warm, playful love song about a couple who feel completely at home with each other. It opens with a tongue-in-cheek nod to "our contemporary philosopher, Ari the accordion player," before settling into the real subject: the small, everyday comforts of being together, a good-smelling room, morning coffee, a familiar accent.
The chorus turns to longing (saudade) when they are apart, and the promise that a kiss from their partner is enough to make them follow them anywhere. It's a piseiro track built on domestic affection rather than drama, closing with a shout-out line dedicating the song to someone named Nanã.
