The current revolution in Yemen has presented an opportunity for the collective art of the people to emerge. These are some of the nasheeds [songs]. The page will be updated as they become available:
Al Sha3b Al Arabiyy Akhtalata (The Arab people have merged)
Ahadna Allah (We have made a pledge with God)
Liwaa Lil Thuwar (The banner is with the revolutionaries)
Itha Al Sha3b ( When a people . . . )
Ya-ezz Ya Dhila (Either dignity or humility)
Law Ana Damee (If my blood)
Kul Ma Zidna Shaheed (With every martyr)
