your brain isn't wired to like it... when you're an infant, unless your mother played music on headphones you like sounds that remind you of the womb...

it's an aquired taste i guess you could say... ever notice alot of shows you watch on tv, you weren't really intrested in at first then they grew on you?

music can also relate to us on a spirital level alot of times, remind us of pain, but in a good way, or remind us of good times, we tend to associate events and even whole parts of our lives with songs, music, bands and even genre's...

it just grows on you....

then of course there's the lyric aspect.... songs with deep meaning to you because of the lyrics... like the song is an extension of yourself that you were never before really able to experess or even comprehend. almost as if, the creator wrote that song just for you... it makes you feel warm, fuzzy and happy inside.
