If you are using the firefox web browser, I would recommend you to install this add-on: https://addons.mozilla.org/en-US/firefox/addon/3349 In this case, you can go to any lyrics website and simply scroll over the lyrics for the hanyu pinyin. I'm using the Japanese version right now and it's really good at identifying the kunyomi and onyomi readings. So I think the Chinese version would be even better!

I have never seen such a website.if you indeed want to learn the chinese song,I can help you .You can tell me the song`s name .i can translate it`s lyrics into pinyin for you

there are many web sites for mandiran,but I don't know its lyrics are pinin.If you want to get the pinin lyrics,you can take the chinese lyrics here,I can help you translate it.

haha 姐姐,Ask me,you will get what you want.

i dont think anyone can find the web site you wanted.
