French colonization of Algeria changed the organization of society, producing a class of poor, uneducated urban men and women. Bedoui singers mostly collaborated with the French colonizers, though one exception from such collaboration was Cheikh Hamada. The problems of survival in a life of poverty were the domain of street musicians who sang bar-songs called zendanis. A common characteristic of these songs included exclamations of the word "raï!" and variations thereof. The word "rai" implies that an opinion is being expressed.
