How do you get songs purchased from the mobile itunes store on ipod touch to itunes?

I purchases music on the mobile store, but they do not show up in itunes. Is there any way to locate these?|||hey dude, i have an ipod touch too. What i think you need to do is once you have hooke your itouch up to the computer and go to your itunes. Click under file then Sync (your name's) ipod. I havent tried the wireless itunes yet but at first i had trouble getting new pics. onto the itouch because it sometimes doesnt sync itself.
