This is a simple song by Wáng Lìhóng 王力宏. It’s called just that: yī shǒu jiǎndānde gē 一首簡單的歌 (“A Simple Song”), which can lead to all sorts of clever lines if you’re ever asked what you’d like to sing for everyone (it happens in China–not “Would you like to sing?” but “What will you be singing?”).
After much deliberation, I’ve decided to actually provide the link for you to download the mp3 by doing a search at Baidu) As much as I don’t think Western artists would appreciate free downloads of their music, this is China and “rù xiāng suí sú” 入乡随俗, right?[Download not found]
