Import play counts from last.fm

iTunes has this addon of sorts called iTunes Store file validator which has the very useful ability of "reverse scrobbling" as they call it. It basically imports the play counts from last fm back into itunes.
I think this could be a useful addon which would allow people who have lost their collection to get some of their data back. Additionally a rating system based on loved songs could be implemented to help build or rebuild a rating database.

Im sure there are many many people who have lots of info stored on last.fm and this is one great way to put that info to use.
