Swin' sweet?
 

This is a song from few years ago: It starts with repeating a verb: Swing swing, swin' swin' or maybe swim swim I am not sure because english is not my first language. Well; the female singers has a really soft and calm voice. Along the lyrics it makes rymes with the first verse, like ring ring (the sound of a phone). Somewhere she says butterfly. And then she sings let swin' or let sweet I,m not sure ,and she ends singing Oh let (or get?) swin'.
Thank you!

Thanks dude, but a woman sang this

Oh.. my bad.

It isn't yet because it lacks some parts. Also in one vers the singer says I know you love/like me Darling or something like that and i aint sure it would pass with the style of that band haha

I found it: It is Beneath the Milky Twilight

You mean"Kiss me"? Pretty song. Glad you found what you were looking for.
