exactly what i experienced.i think its mainly what the music is linked to in your mind.for example:i am married and settled,its 20 years ago but theres a certain track that was a "our song" with my first girlfriend,and it still brings feelings to the surface,even that its not present anymore,i am not interested in even how my first girlfriend is,i dont care. think the brain does build links to areas in the brain where feelings grow,and this is saved for life.
(lymbic system)
another track makes me aggressive no end,without being aggressive in its style or genre,but i know why,and its a topic i dont care about now,too.
our brain isnt developed for media right now,too much hunting and killing left

pure happiness from those i get,young skywalker...
