I don't know if anyone realises this, but its one of the biggest reasons that ACIII is not memorable. Notice that AC1, 2, Brotherhood, Revelations, even Bloodlines, had music always playing in the background. Now we get a silence in every city that makes them unmemorable. I believe its the reason ACIII didn't live up to its franchise. I was hoping for a patch that puts music in or anything like that. That would be amazing.

indeed :P

It seems like we're the only people with this problem since no one has a fix yet :S
