First of all Heavy Rain is a video game which is exclusive to the Playstation. I've played it and I can't help but love the music! The game is about a serial killer killing off young boys when there is heavy rain, hence the title. The music sets the tone for every scene whether it's a death, chopping your own finger off or checking out the new apartment with your lady(if you get the best ending).
It makes some scenes super intense and panicky and you feel as if your the one that's about to die or it makes you feel really sad and want to cry buckets.
Here is my favorite song out of them all. It's a little bit creepy but this is when you have to decide if you want to cut your finger off with the dull knives you find around the house or not in order to get the next set of letters to complete the address in order to find your son. The quote from this scene "How far are you willing to go to save your son?" paired along with this song and the animation of Ethan really made me tear up.
This is the happiest song of the bunch. They played it in the beginning where your life seemed perfect and again in the end where Ethan is picking up the pieces to come around full circle.
These songs are all really beautiful and it makes me wish I could play the piano just to play them.
