As a musician and music teacher I can see that these girls make a lot of money for their record companies. They don't sing though. They just prance about and sing the odd few words here and there. I just wish I could take Hadam and co to England and be her manager for the X Factor. I bet they earn more than 2.3m won per month teacher's salary. It's the same for similar western pop stars like Lady GAGA, Britney but at least they sing.
