My dad thinks that all electronic music is just random sounds and isn't proper music at all.
He doesn't like it and he will never make an effort to understand it so he will forever view it as random.
Remember, just because you cannot see the pattern, it doesn't mean that there isn't one. What it means is that you cannot see the pattern that is all. Probably this will make it that you don't enjoy the music but that alone is not enough to say it is just random.
When I think of random music I imagine myself at a piano just hitting whatever key I like. I wouldn't put darkpsy into that category even if I don't really like it that much. I prefer nightmare trance
