It's not to say that boy bands aren't also guilty of hiding behind generic sex appeal (who do you think you're talking to, here). But when it comes to the girls, its much more black and white -- and I think now Korea is starting to realize that girl groups can be a little more...well, grey.
You can absolutely look at EXID as Survivors in a notoriously shallow Girl Group game and can also compare them to another girl group -- TAHITI -- who recently dropped a brand new song called "Phone Number". On paper, the song is catchy, sexy, and shows off some talented vocals. Its much akin to the doo-wop-pop sound heralded by Meghan Trainor here in the States. But when you take a peek at the video, the appeal of the song gets drowned by the utterly blatant sex appeal offered up -- much of which was identified with EXID's "Up & Down" (the painted on leather pants, the bending-over choreography).
