This is "You Suffer" by Napalm Death, on the album Scum. It's in the Guinness Book of Records as the shortest recorded song ever. It is precisely 1.316 seconds long and consists entirely of the lyrics "You suffer, but why?", although it is very difficult to hear.
I don't consider it a song. I found it hilarious that such a thing exists. I couldn't imagine what was going through their heads when they decided to put it on the album.
