I came across this topic when deciding to buy the regular Full Boost or premium G sound version. I see that it supports custom BGM which would make premium g sound version a waste then right? How does it work though? Can i basically just put all these songs an a usb and plug it into the ps3 and the game will find the files to use in-game? Sorry for so many questions, I just want to make sure I'm not losing out on the premium G songs.
