On its playfully named 2006 holiday album, the popular gospel duo Mary Mary (aka sisters Tina and Erica Campbell) offers up a charming set of Yuletide tunes. While some songs on this celebratory outing are secular ("Have Yourself a Merry Little Christmas"), the bulk of the songs feature Mary Mary's spiritually inclined, soul-tinged sound, most notably "Still the Lamb" and "O Come All Ye Faithful."
