Song containing lyrics sun how i call her cause we met in summerland?

The song you are looking for is "Malibu" by Miley Cyrus.

Here are the relevant lyrics:

Said she don't believe in shootin' stars

But she believe in shots at the bar

She said, "Call me when the sun sets

I met him last summer and his name was Sean

And he taught me how to dive into the deep end"

Summer lovin' (Lovin'), oh, the summer lovin' (Lovin')

Had me a blast (Lovin'), summer lovin' (Lovin')

Had me a blast (Lovin')
