Well I didn't meant it to be in negative way. Sorry its answering the `how` part of question not `why`, but whatever be the reason of `why`, the final thing that brain finds pleasurable is because of dopamine. For example, lets say a person like classical music but might dislike rap or metal. This is because his brain is accustomed to classical music and the more he listens to it, the more dopamine is released. However, in case of other genres, brain is not accustomed to it and thus the pleasure hormone might not work.
