I just remembered something that I read some time ago, that might be of interest to anyone wanting to continue this discussion. Basically, I read that sometimes when a person spends a lot of time in sunlight, their hair can be bleached by the sun. So "Yuh siddung eena de sunshine wid nuttin 'pon yuh head" could be a sarcastic reference to this fact, (going with Azizi's comments, which are plausible in considering the theme of this song).
