So I was listening to my music on my laptop, while it was not hooked onto the internet and no where near a WIFI connection either. Naturally the Last fm thinger comes up whenever I have my itunes running and for some reason I left it on even though I knew I wasn't on the net. Just got here a little while ago, signed on to the net with my laptop and all that music is updated and showing on my profile.
So I guess it saves the info for the next time you're online?
Sweet!
