I have no idea what the title has to do with this post but i guess it does pertain to music.  ask your self what music entails.  does it entail the emotion of the writer?  or maybe the artist?  maybe both?  what if music has the emotion you put into it?  could your emotion ruin a thing that's as beatiful as the sunrise?  could your own perception destroy something that you should hold dear?  take for example the appreciation of the sun.  if you think it is evil then the sun...a nice and bright thing becomes dark and foreboding of evil.  does that make sense?  or how about this example you're reading a book and then you don't like a character that just was introduced.  then does the whole book become ruined or is it that you feel taken aback from this annoying character that won't go away.  does that clear it up?  i have no idea what the point im trying to get across is.  but i must have some point.  but anyway, i guess it could be that perception is only affecting what you see and not what you feel....something like that i guess.  lol i don't even know what i mean anymore....^_^  explain to me what i mean if you know what i mean
