Syncing purchased iTunes song to another iPhone?

I have a work phone that I want to sync all my purchased iTunes songs to. It has a few already there somehow, but only ones I just recently purchased. How can I wirelessly sync the rest of my purchased songs?

If youre using the same account you can go on your iphone to the itunes store and navigate to the more option at the bottem of the screen. From there click purchased and all your songs will be there ready for you to download.
