Can someone please give me a general idea of what this song is about? I don't need a full translation, just an overview of whether they're criticizing the Egyptian government or something else, and if they're referring to something specific or not.

Song here:

Lyrics here:كلمات-مهرجان-ل...#1610;ة/

Also, what is the song they are sampling at the beginning? I know I've heard it before, but can't place it. Something by Mohammed Abdel Wahab, maybe?
