I finished Control the other day and the end credits song is a real banger:
Fear of A Blank Planet by Porcupine Tree:
It's hard to say why exactly, but I feel like certain songs just really work as an end credits song. It might not even be a song that you'd listen to normally, but it fits really well as closure for the game you just finished. I remember thinking the same thing about the songs at the end of Dishonored and Driver San Francisco.
What are some of your favourites?
