Music played a key role in mobilizing the 2011 protests at Tahrir Square against President Hosni Mubarak which led to the Egyptian revolution. "Ezzay," meaning "How come?" by Egyptian singer and actor Mohamed Mounir is considered one of the most popular songs associated with the protests. "Irhal," meaning "Leave", by Ramy Essam became an internet hit, and was subsequently described in the media as having become an anthem for the revolution.
