I was most interested in item 4, a song by the Tunisian Jewish singer Habiba Msika called "'Ala Sarir al-nawm dala'ni."
Habiba Msika (1903-1930) was quite the sensation in Tunis in the twenties, wearing Paris fashion when the norm was for respectable women to be covered up, taking up with lovers in a fairly public fashion. In 1925 she appeared onstage in a production of Romeo and Juliet, playing Romeo opposite the Libyan Jewish actress Rachida Lotfi's Juliet. Their onstage kiss caused an uproar, and her côterie of fans, known as the "soldats de la nuit," who included many young Tunisian dandies, had to rescue her from outraged members of the audience.
In 1930 a jealous ex-lover entered her flat, poured gasoline on her, and set her on fire. She died the next day. (And you can read more about her fascinating career here.) Tunisian director Salma Baccar made a film about her, La Danse du feu (1995), which I would love to see. (This might be a clip from the film.) And the blog Jewish Morocco reflects on how Habiba Msika is "remembered" in Tunisia today, here.
(And someone please help me with a vernacular translation of that song!)
Added, a few hours later. See the comments from Hammer. The song could be translated as "On My Bed He Spoiled Me." I.e., he shtupped me. Hence the "taboo" nature of the song.
