According to this post, the members of the girl group T-ara are so busy acting in dramas, movies, and variety shows that they can’t sing on stage or record in the studios.
Jiyeon has already been in a lot of movies and dramas, Eunjung has been in a drama and preparing for a movie, Hyomin has been preparing for a drama, and Qri, Boram and Soyeon have been regulars on variety shows. When album activities occur, the girls become very busy.
A representative said, “T-ara’s Hyomin is preparing for a drama shoot and future individual activities,” he said, “in this case, it means they girls can’t regularly be on stage or record often or else members would be missing and that’s why we recruited a new member to hold activties and keep interest in T-ara and not the dramas/movies.”
I thought that they are, you know, singers. It reminds me of the time that Uee, of the girl group After School, was so busy with her acting that she couldn’t join After School in performances.
This kind of thing, combined with the fact that most girl groups only have one or two members who can really sing well, reinforces the notions that:
a. to be a “singer” in South Korea you don’t need to be able to sing well
b. South Korea doesn’t really have singers and actors like other countries do. That is, in other countries, singing and acting are professional careers that require ability and specialized training. In Korea, there are just “celebrities” who both sing and act, but don’t dedicate themselves to either and don’t do either particularly well.
