From Transnational Broadcasting Studies (TBS) 16, a very useful article: "The Fool Sings a Hero's Song: Shaaban Abdel Rahim, Egyptian Shaabi, and the Video Clip Phenomenon," by James R. Grippo, UCSB PhD candidate in ethnomusicology.
Here's the last paragraph:
Contributing to ‘Abd al-Rahim’s controversial success is his social positioning as the next superstar descending from a historic line of political sha‘bi singers in Egypt. Finally, ‘Abd al Rahim’s success must be understood in the context of the West’s loosely defined War on Terror. The perception of cultural and political attack from outside the Arab world has sparked the need for amplified voices speaking sympathetic truths to a self-consciously cornered Muslim population. ‘Abd al-Rahim’s uncanny sense of Arab anger and frustration has enabled this illiterate ironer from Mit Halfa to become one of the loudest of these voices.
