Korean pop music groups pretty monotonous. It's not good, not bad, its just such a feature. Btw, another feature of those groups is the fact what these groups is not about music, but about show. Yes, they sign, they shooting in series ang films, participate in television programs, and, of course advertise everything in the world - cars, alcohol, game consoles, everything. If you newbee in kpop - you will not find a difference between the many of these groups. But if you make a mistake and try to go deeper ...
Okay, its my one of most loved korean pop group - Sistar. They was make best summer hits on the korean scene:
But, sometimes they was make something little dark.
And now they are disband. But they main vocal, Hyolin, continues his singing career alone.
