Skeletons in the Closet is the second compilation album by Finnish melodic death metal band Children of Bodom, released on 22 September 2009 through Spinefarm Records. It consists of various covers of songs, most of which have been released on other releases such as B-sides on Children of Bodom's singles. The album only contains four unreleased covers for the songs "Hell Is for Children", "Antisocial", "War Inside My Head", and "Waiting", but the previously released songs are remixed and new details can be heard.[citation needed]
