After peaking as high as No. 2 in December 2009, the all-star charity ensemble Band Aid re-enters this week at No. 1 with “Do They Know It’s Christmas?” Also re-entering: Madonna’s “Santa Baby” at No. 12. Seems Christmas is truly in the air despite the grim times. Elsewhere, Max Barskih moves up ever closer to No. 1 with his new single “Tequila Sunrise” at No. 2.
