Thank you for your comment.
I know that Chinese version is requested also in the Microsoft Store Reviews. To translate into Chinese, it is nessesary to translate from Japanese directly, or from Japanese to English and from English to Chinese. But I have no friend who can speak Chinese, so translation is very difficult for me now.
TuneBrowser seems to be used widely by Chinese speakers (many thanks!). I hope it will be translated into Chinese in someday.
Thanks.
