Released one week after the Glee holiday album, Vol. 4 collects highlights from the first half of the show's second season. Songs from the "Britney/Brittany" episode -- the most watched episode in the show's history -- are featured, as are performances by newcomers like Gwyneth Paltrow (who plays a substitute teacher) and newcomer Darren Criss (who leads a rival glee club).
