Sync from Iphone to IMac
I've got a detailed playlist on iTunes on a PC, synced to my iPhone. How can I get that exact same playlist (all songs in the correct folders, including some podcasts) onto my new iMac? Can you plug in your iPhone and sync it in reverse? Or do I have to go back and recreate all those playlists (hours dragging songs into folders)?
iMac (21.5-inch Mid 2011), Mac OS X (10.7.4)
