Podworks Doesn't "see" all my music on my iPhone!

I have an iPhone that has "iPhone purchased" songs on it and I need to get them off to back them up. I've tried using the "Recently Played" or "Purchased" playlists but, my most recent songs (1 Album and maybe 10 individual songs) don't show up in PodWorks. Is there something I'm missing? I've even played all the songs again from the phone to be sure they were the "most recently played" items, still no joy. Please help. I don't want to have to buy them again :(

If your wondering, I screwed up the iTunes library I was syncing to, BEFORE, I backed up my iPhone. I'm an idiot!

Please help
