While playing Batman: Arkham City, Crazy_S was interested to see if you can play your own music on your PS3′s hard drive. Crazy_S tested it out and was surprised that Batman: Arkham City allows you to play your own music, while playing the game. During the game, press the “PS” button and go to your Music on the “XMB” and select your song to start playing. Press the “PS” button to get back to kicking ass, but now with your own music in the background. Now everyone can enjoy listening to “Can’t Touch This,” while taking down a large group of thugs.
