[Discussion]f(x)

f(x) (Korean: 에프엑스) is a five member South Korean girl group formed by SM Entertainment in 2009.

The group members have also been nicknamed "function girls". The group made their debut on September 1, 2009 with release of a digital single "La Cha Ta" (stylized as "LA chA TA").

so the one in black in the top pic, that's a chick? if so they should call on that chick next time there's a drama about a girl posing as a guy, b/c that is very convincing.

I only like a couple of their songs, so I don't consider myself a fan. But I ♥ Amber.

Woah, we didn't have an f(x) thread before? Anyway, f(x) is gonna come out with their new mini-album 'Electric Shock' on iTunes on 10th June, and in stores on 13th June. The teaser photos are definitely intriguing, and although I'm eerily reminded of SHINee's Sherlock's teaser pics, I'm still pretty darn excited ^^ On a side note, I was hoping it would be an album and not a mini album though :o

Sounds quite good :O but the ending reminded me a lot of SHINee's Lucifer

I'm not really into f(x), none of there songs have really appealed to me beyond that I like Electric Shock.

I am really impressed with f(x)! I've really like the majority of their songs and I think Electric Shock is great, but I just don't like that part of the chorus. when they say "nananananana". That is mildly annoying.
