I'm in Korea right now and I see almost all Chinese characters on signage and newspapers in traditional characters. Pretty much the only simplified characters I see are on literature and signage directed solely at tourists from mainland China. I highly doubt many Koreans can even read simplified characters. Perhaps people who are learning Mandarin here might learn simplified characters as they usually learn Beijing dialect but in terms of public usage it's pretty much unseen. I learned a bit of Mandarin in Korea in school and I was taught in traditional characters from an ethnic Chinese-Korean instructor, but that was years ago. I suppose it's possible things have changed with the rise of China and improving bilateral relations.

Really? I've always felt Cantonese is too "choppy" for music... I actually like Taiwanese music, at least some of it. If they start singing in Hokkien I get totally lost though.
