Shawiyya (Chaouia) is a Zenati Berber language of eastern Algeria, spoken inland on the Sahara-facing side of the Atlas Mountains. While spread over a far larger area than Algeria's other main Berber language, Kabyle, it has only about half the population (1.4 million or so). Unlike the Kabyles, the Shawis, as their Arabic name suggests, were traditionally seminomadic (transhumant, to be exact); after independence, many seized the opportunity to settle down in the cities, and, from what I hear, this major change of lifestyle led to widespread language shift to Arabic. Shawiyya, like other Zenati dialects of northern Algeria (Chenoua, Bissa, etc.), but unlike Kabyle or the Berber varieties of the Sahara, has the interesting sound change t > h initially in many contexts. Anyway, I found a Shawi-language-focused blog the other day, to my immense surprise, which I figured was worth linking:
Awal nu Shawi
It seems to mainly post lyrics, sometimes with translations.
