Since iTunes has no way to sync with my Motorola Droid, and all of my music is on my Macbook Pro, I recently tried out DoubleTwist. It detected my Droid right away.
The problem is that when I chose to sync all of my music, DoubleTwist also synced all of my podcasts, which quickly filled up my sd card with stuff I don't want on there. Is there a way to have it only sync my iTunes music library and ignore podcasts?
