[quote name='Thomas96']Sony needs to read that patent a lot closer, because MS patented an "application" that can play music in game from the console's hard drive. I thought that Sony was using their "Operating system" - aka XMB to play music from their hard drive. So the question is.. XMB an application or a operating system. because from my knowledge XMB is an operating system, not an application, and thus I should have my Custom Soundtrack.[/QUOTE]Actually, it's pretty much the same way on 360, because it's an operating system being used in-game. It's just something where Sony MIGHT be able to be do something slightly different, but I think the last thing Sony wants is another patent infringement and actually face MS lawyers (who are quite powerful and rich).
