To further my post on March 30 about free music download from Google available in China, I now introduce you to a method to access these free clips using a proxy server when you are outside of China, smartly suggested by Nelson. Here is a blog post about how to set it up, and I would not repeat it. I tried with IP address 184.108.40.206 (port 8080), and it worked out quite well.
Something worth noting are that you have to use a server located in China, and you also need to know Chinese to read the Google China website (I don't know whether Google Translate works well here). One last thing: Don't expect this download to be speedy.
If you would like to investigate more on how to find http/ftp music download, also watch this video on YouTube.
