The Sarah Connor version of "Under My Skin" came out August 1st, the Korean version in September, though Wikipedia says that both Sarah Connor and the Korean boyband Dong Bang Shin Gi had bought and recorded the single independently of one another.
Earlier we learned that the ubiquitous "One More Time" was actually a remake, and many Koreans are surprised to learn that the 2005 hit "Maria" is a Blondie cover. A couple of years ago Lee Hyori got in trouble for ripping off Britney Spears' "Do Something" for her "Get ya." Most people from one continent don't follow the trends of another---be it music or movies or something else---so there's usually no damage to the time-space continuum. Just some embarrassment when one recognizes the other.
