double twist reads your itunes play lists and transfers them but only once. if you change a itunes play list it will not read it again.
Do we know of a program that reads the itunes library and playlist every time you open it?
That's right. Now I remember why I didn't like Double Twist. It pretty much required you to sync your whole library - or at least I couldn't figure out how to disable that. My library is way too big for my Droid.
I believe the Motorola Media Manager does this.
