All You Need is Dark

There's nothing you can do that can't be done
Nothing you can sing that can't be sung
Nothing you can say but you can learn to play the game
It's easy

There's nothing you can make that can't be made
No one you can save that can't be saved
Nothing you can do but you can learn to be you in time
It's easy

All you need is dark
All you need is dark
All you need is dark, dark
Dark is all you need
