Tiger Hu/ aka Anson Hu / aka Hu Yanbin

There are several songs by Tiger Hu that I can't get on iTunes in the US.  Probably licensing issues, who knows.  

 For example,  I've looked through OSTs to see whether the song "Moonlight" is available and all I can find is youtube user-made vids for the song on Qin's Moon OST, and Stormriders OST.

ThankDoes anyone know where I can get legal digital copies of Hu's music in the US?s :)

Thanks :)
