Mousa is famed for writing a dozen notable songs in the late 1980s and early 1990s for prolific and popular Assyrian singers such as Sargon Gabriel, Ashur Bet Sargis, Janan Sawa, Linda George and Juliana Jendo, among others.

[1] Adwar Mousa's dance songs "Narineh" and "Wye Wye Minakh", which were written for Sargon Gabriel, still remain widely covered and played in today's Assyrian weddings and jubilant parties.

[2] His other folk dance songs, such as "Hoy Jano", "Hatkha O Atkha", "Kewat Ya Shimshi" and "Barowen", are also immensely covered in Assyrian parties, which have gained popularity since the early 2010s, despite the fact that they were composed in the early 1990s.

At over 1.6 million hits, "Kha Yoma Kheshli Khlola", written by Mousa and sung by Bassam Slivo, is one of the most-viewed Assyrian songs on YouTube.
