I know TVB borrowed instrumental music from Himekami, S.E.N.S, Kitaro and other places. I might be just the few that fell in love with these music and became a vivid reminder for me whenever I listen to this and remember the series I've watched that had it playing in the background. I've collected and bought some of the CDs that have these songs on them.
Below are some music by Himekami, some people might recognize:
