iTunes Music Sync - Solution
My apologies for the delayed response and hopefully this is resolved for you. If not, may I suggest:
- Upload your music to DropBox from your device (load the queue up and let it run in the background while connected via WiFi)
- Install DropBox on your PC and the files will automatically download/sync
- Import to iTunes
This is still rather archaic but beats emailing every song individually (Bonus - a simple way to "lend" music to others as you can send a link from DropBox to share the files).
