If your music is DRM protected, it will not be moved by Double Twist. Needs to be converted first. Easiest way I have found is using DVDVideosoft Software. I do NOT work for them, but have used their products for years, and I can't believe it free....but I digress...
Using their software, convert iTunes (which I hate with every fiber of my soul....and I say that as I am sitting on DMV....) to mp3 format. Then you can use Double Twist to move them...or drag an drop. Since you have a large collection, Double Twist is easier.
