How to get music already purchased on my iPhone to iTunes without plugging in?

Not sure if that is the best way to word the question at hand. I purchased music on my iPhone and accidentally stopped the sync when it was loading to my iTunes. This was WITHOUT hooking up my iPhone, it was just iTunes recognizing that I had new music purchased via my iTunes account and syncing it on its own.

How can I manually sync the way iTunes was trying to, before I accidentally stopped it? I can't figure it out.

Added (1). NEVERMIND… I simply quit iTunes and reopened it and the "Downloads" started automatically… I just really thought I did that already the other day, it's been on sleep.

You device has stopped transferring files when syncing with iTunes. And if you want to stop the automatic syncing, to plug in iPhone and set up as "manually---" in the pop up window. You can also use a iphone transfer software to transfer files instead of iTunes
