Thanks Sean to share this interesting information to us. I changed "Region" in my iPhone from "Australia" to "China" and guess what - there are 2 extra screens appeared in Sugr App - DouBan and LiZhi!
I tried "DouBan" music and actually it works quite well. It would be great if such music stream service can be enabled or disabled in the app itself, rather decided by your phone's region setting - that would be much convenient to select which music streaming service would be used.
But anyway, "DouBan" and "LiZhi" are working now and it really makes SugrCube more enjoyable to me now.
