Kol Et Eleha Enai - כל עת אליך עיני
First time I heard this song, I fell in love with. It's beautiful and melodious. And believe it or not, it's not a Moroccan song. It's origin is from Yerushalayim (or Egyptian) and can be adapted to many parts of the Tefila.
This song is the Hebrew version of the famous Arabic song "Omri Na" composed by the late Sami El Maghrebi. The words are beautiful and the maqam is Nahawand (similar to Sahli). The tune can be sung for Kadish or Kedusha.
