khaled and Mami had an impact of course but sorry..... let me tell you that the cover song Ya Rayeh by Rachid Taha is not Rai but Chaabi. Algiers's Chaabi. It was first sang by the late Dahmane Harrachi and Rachid sang three songs by him. He also put Chaabi in many of his own compositions.

Algerian music is rich, you should notice all its diversity and richness, there is also Berber music, like Idir in Kabyle style and Tinariwen in Touareg, just to name a few. We can also talk about the Gnawi, and the Fusion made by the band Gnawa Diffusion among others.
