Is there any way to manage an external USB drive in iTunes as if it was an iPod? Specifically, have it appear as a device in iTunes, and be able to specify which playlists, etc., should be synced to it.
The use case is managing a USB stick that I use in my car. Currently, I have a smart playlist that I want synced to it, and every time I want to make an update, I delete all the files on the USB stick and then copy the playlist over, which is far from ideal.
