I think your topic would be more appropriate at the Media Centre subforum (under "Entertainment") as the General Game Music Discussion subforum deals with video and computer game music, not conventional pop, classical, rock or otherwise licensed music that does not feature in games.
The few exceptions I can think of include the "What are you listening now" thread which appears to be somewhere around... Another thread of some relevance would be game music featured in mainstream culture (e.g. commercials, HK drama serials).
As for your question, I've definitely heard of the singers in the news but have been so out of touch with Mandarin pop music in general that I can't really recommend anything similar. You might have some luck with
HMV Hong Kong for merchandise issues.
Jam it back in, in the dark.
