I was in my early teens when my home city went crazy about Depeche Mode, and this particular album. However, I was a true metalhead at that time, and anything lighter than Slayer was absolutely out of my sphere of interest. It was much later, through revolutionary "One Second" by Paradise Lost, through Depeche Mode's guitar-driven "Ultra", that I came to appreciate "Music for the Masses" like this album fully deserved.
No matter what some say, to me this is one of those perfect albums in my collection. It's perfect because it doesn't have a single weak track in it. The songwriting is excellent, and every song has its distinctive mood and melody, that will sound in your head for hours. This music is a blend of gothic depressed darkness and melodic accessibility and imaginative rhythming of synth-pop. But it never gets repetitive, because the variety of the songs is so good. From a danceable "Never Let Me Down Again", to grandiose "Sacred", to melodic melancholy of "Little 15", to disturbing instrumental piece "Pimpf", this record has got it all. The band demonstrates imaginative use of synthesizers, and David Gahan's voice strikes with depth and sensuality. This album is not actually dancing music, but rather is intended to be appreciated through thought. Intellectual electronic music, if you wish.
I think that through these years "Music for the Masses" managed to keep its appeal and beauty, and unless you hate this particular genre, you'll like it, just like I did eventually.
