HI i have an xbox 360 pro model and I have a sandisk cruzer micro 2gb and I use it to play music on my xbox. However it is really annoying putting in the drive and playing music and I cant start the music when im playing a game or it will take FOREVER! SO i learned about this thing called Optional Media Update so I can sve the songs onto my hdd cause I cant save them now. I dont have live now but I will be getting it soon so I just wanted to know if the update was free or not?
