I know some! This one, for instance, is extremely nice and cute :D, makes me try to learn the language but then I see the characters and I come back to my senses! xDDDD 曲婉婷 - 我的歌声里 https://www.youtube.com/watch?v=w0dMz8RBG7g

what kind of songs do you want to know about?

Maybe my pinyin is incorrect, but my answer is "Si le dou yao ai" by a Taiwanese band called 信乐团, Xìn yuètuán... 2007... brilliant melody
