Title edit

According to Mark Jansen, "This title refers to the end of an era. Mankind can no longer stick their head in the sand for the things that are happening around us. We are facing many challenges. There is an enormous tension between different religions and cultures, wars, natural disasters and a huge financial crisis, which is getting out of control. More than ever we will need each other to overcome these problems. As we are all connected; the universe, earth, nature, animals and human beings, this period in time will be the prelude to the end for those who still don't want to, or simply won't see it. A Requiem for the Indifferent but also a possibility for a new beginning with great new chances!"^[1]

General response to Requiem for the Indifferent was positive. AllMusic stated that the album "is a typically elaborate and ambitious affair, incorporating copious amounts of choral work and classical arrangements into the band's neatly established blend of goth, progressive, power, and symphonic metal."^[3] Natalie Zed of About.com staff considers Requiem for the Indifferent "a transitional album for the band", which tries to expand their musical range experimenting with "weird" riffing and new combination of vocals, while "losing none of the richness that has gained them fans."^[2]

There was an error with all physical copies of the album's first edition, in which track 13, "Serenade of Self-Destruction", is an instrumental version without Simons and Jansen's vocal tracks. As compensation, Nuclear Blast Records decided to make the track (with the vocals) available as a free download. The glitch was corrected in the digipak versions.^[6] This instrumental version has a small part of vocals from Simone Simons at the very beginning,^[7] which makes it different from the total instrumental song released separately, on which you only hear the piano at the beginning.
