The fourth, fifth, and sixth box sets dedicated to compiling all of Depeche Mode's single releases were put out in 2004, 13 years after the first three originally appeared. All of these sets provide a convenience for hardcore fans since they provide each single in its own slim jewel case. Needless to say, those who bought the original singles as they were released will be flustered once again. The fourth set, covering 1987 through 1990, includes the "Strangelove," "Never Let Me Down Again," "Behind the Wheel," "Everything Counts (Live)," "Personal Jesus," and "Enjoy the Silence" singles. At this point in Depeche Mode's career, each A-side was being remixed several times over; when not filled out with live material or the occasional nonalbum track, the discs contain anywhere between a few and several alternate looks.
