Misora was indeed one magic artist over centuries. I am sure you can get very close to her talent after some practice because of your born capability. You should thank your parents for that. :-)

I don't have other materpieces in mind right now. But I do like Sen Masao's 千昌夫 early song "Hoshikague no Waltz" when he was young. The emotional touch was expressed irght to the point. The emotional force in this song is not high pitched like many Chinese songs but is forceful from within. I don't know if this song is right for you to sing though.

Sorry I cannot write in Chinese. Have a great day!
