I went through a phase of listening to ambient dark techno and also death metal, but it didn't last long. I found its rythms and sound effects to be like a sugar rush where you just want the next sound effect, but Now I just listen to Gregorian chant which has no sound effects, but instead has true atmosphere and gives goosebumps, I want to replace all my library with Gregorian chant now. After a while you get tired of sound effects. And another thing, they are always mathematical, the drums or sound effect beat in the back ground is always in intervals of 4, or 8. That fails because it gets old because you predict it.
