I have seen many people play the vocals of a song like leads on the guitar.

There is not much guitar in my country's music so I am trying to learn how to convert the vocals of songs into guitar lead tabs.

Is this possible? if so how?

For examaple: The vocals of this song interests me and i wish to play it on my guitar.
