talking about kareoke; it wasnt like in front of thousands of people but i did go to kareoke with my friends very often and sing japanese songs..But my friends have no clue to what I am singing since none of them know japanese but me lol
I also went to kareoke in Japan when i went there this summer...I couldn't read most of the kanji(cuz i'm korean) that was coming out on the screen but i knew some of the hiragana and katagana so that helped me a LOT...and i did memorize most of ayu's songs...
But I don't think I would be able to sing in public....My face would probably turn into a tomato..
