Thank you. Now, when you say that I only will be able to open it on my Mac, does that mean I won't be able to open it on my iPod? Here is my situation, maybe there is another solution, I record music professionally, so I like to put the studio tracks on my iPod to listen to when i have the chance and then make changes or learn the songs better, whatever. However, sometimes I let people listen to my iPod but I would rather they not have access to these tracks that are not finished or released to the public yet. So I would like to be able to put these tracks somewhere that only I have access to them but I can freely let someone use my iPod for everything else that is on there. Any suggestions? Thanks!!!
