Well people grow up and the way they see and hear changes,thats what i believe.
Thats what happened with me.I was listening to black metal when i was young,then to trance when i started taking loads of drugs and now i just find IDM to be much more mature and,sometimes,much more psychedelic,in the general meaning of the word.But that doesnt mean i got bored of trance.Or black metal.I still love 'em.
