Hey guys! I was just wondering... is it possible to take; for example, the ISO for Just Dance 4 and put the DLC songs into it? I do realize that you have to download the songs on your own (because they're marked for your console somehow) but if you have them already could this be done? Or maybe taking songs from other ISO (JD3 or JD2) and putting them into JD4? Thanks in advanced for your answers ^^!!!
