Since i know. All the ps3 games has a 50gb blu-ray disc. Then, is the music in all games now streamed like mp3 and ogg? If the music is sequenced. Why don't corrupt some audio files in the ISO file? Then play the game with the corrupted audio files, and see what happens on the real console.

Metal Gear Solid 4 : guns of the patriots
Final Fantasy XIII
