Important thing first: I do not trance easily.
Just thought that that was important to note, also different people react differently so your experience might not be the same as mine or anyone else's.
After listening to it for a while I have noticed no obvious change, though I have found myself, on occasion, closing my eyes and just sitting there listening. After a long time listening I do sometimes feel a slight effect almost like a force inside my skull around above my forehead and the back of my head. Not sure if this is an effect of the file 'blocking' or making it harder for me to use my brain.
Also I love Jekket's voice and the delivery (I mistyped that as 'devil'ery at first; maybe it was correct to begin with? :P) is superb. How I wish he'd make an update, hopefully with him enhancing the effect and/or making us blow our brains out whenever we orgasm.
