Ok, let's go and cheat iTunes~
So, to move your music from your iPod to the computer (I'm not entirely sure about this, I haven't tested it so... Yeah~)
First step: Go into iTunes (With your iPod connected... Duh)
2: Make sure your iPod is on manual (As in you can move music to it manually)
3: Press the music tab on the side bar.
4: Now highlight the music you want to move to the computer
5: Ok, so now comes the confusing part. You need to drag these songs to this little thing in the side bar that's underneath your iPod picture. It should say 'Purchased'. Drop it there.
6: Once it's all moved, right click on your little iPod picture
7: Now click 'Transfer Purchases'
8: This will delete the purchases off of your iPod but put them into your normal library (This happens with EVERYTHING you downloaded on via your iPod so be prepared to put it all back on)

I suggest not trying this :3 it probably won't work XD... Yeh XD
