The O.C. Mix 3: Have a Very Merry Chrismukka, various artists (Warner Sunset)

Fans of the Fox TV show are familiar with the children in the blended Christian/Jewish family creating "Chrismukka," their very own unique holiday observance. This collection of alt-rock-pop is in keeping with the show's frequent use of such material in the soundtrack, although the material ends up much more Chris than Mukka. Much of this material has been heard before, including Leona Naess' "Christmas," Ron Sexsmith's "Maybe This Christmas," Low's "Just Like Christmas," and Jimmy Eat World's cover of Wham's "Last Christmas." Other contributions include "Rock of Ages" by Ben Kweller, Rooney covers Slade's "Merry Xmas Everybody," "Christmas With You Is the Best" by the Long Winters and "Christmas Is Going To the Dogs" by the Eels. UPDATE: This is available as disc or download, although the download version doesn't include the Rooney song.
