To continue overuse of a holiday cliche, "'Tis the Season" to listen to Christmas songs, and I thought I'd list a few CD's that I enjoy:
Happy Christmas - Various
Christmas too beautiful for words - Stan Hinshaw and Tim Neely
Christmas in Heaven - Various (Out of Print)
Christmas in the Vineyard - Vineyard Worship
I've also been practicing singing "O Little Town of Bethlehem" to the tune of "America the Beautiful" and vice-versa (Try it, you'll like it!).
