Have you guys ever heard of the English Usage Audio Archives, which let you (and I quote from their site) "Listen to the sounds of English from across the USA and around the world".

Reminds me of when I went "down under" and listened to a news broadcast shortly after landing. I -- of course -- understood all the words spoken, but had absolutely no idea what the broadcasters had said. Same with reading newspaper articles. It took about three days for my brain to translate what I consider "Australian English"!
