Two things you can count on when it comes to Christmas: Santa Claus and new Brett Eldredge holiday music. Yesterday Brett announced that a new holiday music collection was on the way. "Merry Christmas (Welcome To The Family)" is the third holiday album from Eldredge; the eight track collection features duets with Idarose and Kelly Clarkson, who appears on the first track to be released from the album, "Sweet December." The album comes out September 27.
