Sting loved her since he first bought her services, and promises he won’t talk down to her or treat her like an object (unlike those OTHER men).

Sting is telling Roxanne that she doesn’t have to walk the streets as a prostitute anymore; it’s in her past.

Police lead singer Sting wrote the song, inspired by the prostitutes he saw near the band’s seedy hotel while in Paris, France, in October 1977 to perform at the Nashville Club.

A reference to how many rappers including himself, hold their nuts with one hand while holding the mic with the other.

This could also be yet another reference to MJ, as when he danced he’d quite often grab his crotch, or place his hand near it with his left hand while he held his hat with his right hand.

Jack wants love to hurt badly so he remembers to stay away from it. He was hurt in the past by love, and he wants to continue to think of love as hurtful, a source of pain, rather than let himself fall back into love.

Black is a metaphor for depression. When in a depressive state, everything seems black and dark. Winehouse was known to suffer from depression from a young age.

Black is also often associated with death, so this may indicative of the singer coming to terms with the “death” of the relationship – a mourning of sorts. This coincides with the music video, where the singer attends a funeral.

“Black” is also the end result of her drinking. In attempting to escape from depression brought by her boyfriend, she blacks out.

‘Back to black’ may also allude to returning to heroin use (i.e. black tar heroin), in which case ‘troubled track’ from two lines previous is suggestive of track marks that remain from injecting heroin.
