To your latter question, you have to log in, in order to download the free songs (with an Apple or AOL acct). So I think unless you find a way to fake it

you cannot get the free music if you live outside the iTMS service area.
I just re-did the Internet ITunes Registry thing to find out my big artists. Most of them are opera/symphonic, which doesn't really address what I listen too most at the moment...Benjamin Britten, Gilbert and Sullivan and Giacomo Puccini, came in at the top. My top pop music, which is what I listen to more, were The Cure and The Smiths. None of my hip-hop records, but not such a surprise since most of the people whom I listen to don't have that many albums yet, except the Roots, and I don't own that many of their albums yet

.
I like how the Registry also shows top artists by play. Utada Hikaru came out like 50% ahead of the closest second for me and I only have two of her albums. Guess now I know where I should be spending my money.
