In some areas, the limited edition of The Dark Side was released as Masters of Chant Chapter V leading to some confusion when that title was used for the subsequent album.
On the Limited Edition, the song Engel (Rammstein), featuring vocals by Marjan Shaki, is between the tracks Gregorian Anthem and Ave Satani (The Omen), making it the eleventh track:
The 'Special Rock Edition' featured ten tracks. The notable differences from the standard edition are the omission of three tracks (Where the Wild Roses Grow, Uninvited and The End), the ordering of the tracks, as well as the length of the existing tracks; some are shorter. This edition also includes an extended version of Nothing Else Matters, from Gregorian's first Masters of Chant album.
