Top 7 k-pop bands

I believe most everyone has already heard or/and danced Psy’s major youtube hit “Gangnam style”( in case you haven't, don't waste time and watch it NOW: http://www.youtube.com/watch?v=9bZkp7q19f0), however let us not forget that there is a lot more of Korean music where Psy came from! To those who, like me, enjoy listening to new stuff every now and then, I made a list of my 7 favorite Korean bands/ singers and their “best" songs. Make sure to check them below and let me know which is your favorite K-pop band/ song" 

Galera, todo mundo já ouviu o hit do Psy Gangnam style, né? (Se você ainda não viu, assista AGORA por que super vale a pena conferir: http://www.youtube.com/watch?v=9bZkp7q19f0). Além do Psy, várias outras bandas coreanas também tem bombado na internet e por isso eu fiz esse post com as minhas 7 bandas de K-pop favoritas! O que vocês acharam? 

7- Wonder Girls- Be my baby (English version)

6- SISTAR- So cool

5- A1B4- Baby Goodnight

4- HyunA (4 minute) - Bubble Pop

3- Super Junior- Sorry, Sorry

2- 2NE1- I'm the best

1- SNSD (Girl’s Generation) -The Boys (English version) / Gee  (I'm sorry guys, SNSD is my favorite band, so I can't just pick one song! I had to pick at least the two ones I LOVE the most!!) 

So guys, what did you think of my ranking? Do you have any suggestions?

Então galera, alguma sugestão de alguma banda/ música que deveria entrar para o Top 7?
PS: These is MY top 7, so don't criticise me!
