The recent film "Crossing the Bridge" about the music scene in Istanbul has a stunning performance by Brenna McCrimmon (with Turkish Gypsy musicians, including Selim Sesler) of a Gypsy song from Bulgaria which seems to be addressed by a prostitute to her pimp at the end of a night's work: "come up and get your money..." I would guess Kalan Muzik have recorded it, I'll check when I'm back in Istanbul in a few weeks.

At the other enbd of the spectrum, I included a hymn for repentant prostitutes in my "Embro, Embro" cd-rom (from a whole book of them produced for an asylum for fallen women around 1800), also a lesbian song addressed to a vibrator, etc. etc.

I'd second the recommendation for "My Song is My Own" - there was a companion LP for it, too.
