Why did they choose to only give us the one Diary video for sound, why not all of them?
I know they are accessible on youtube and such, but still, kinda weird decision making there :P

if you want the entire soundtrack, buy collector's edition. that's what I did. period. don't expect if bought standard version. all games are the same. when you buy standard version, it's only game.  
 
by the way, the sound of entire tracks is not suitable during driving. it's annoying. 

I can't see why anyone would enjoy listening to the game soundtrack, unless you're in a haunted house.
