DROP IT! Girls Day "Something"

The new it girls of K-Pop are back for their annual wig donation. The foursome known as Girls Day handed every K-Pop act their retirement papers last year with the uber-catchy "Expecation" and the iconic suspender/butt dance. Now that the girls are kind of established, it's time for a new concept for a new year!
"Something" is a smoldering mid-tempo, disco style track made possible by producers Duble Sidekick. I think that this was the song that Minah was supposed to have for her solo debut, as she has more than half of the lines. I guess because Girls Day had such a career defining 2013, Dream Tea opted for a group comeback. Their budget also has seemed to grow, though I recognize some of the sets. The downfall of this is the leg bouncing dance: everything else is clean and sexy, then awkward leg bouncing. Of course there are going to be comparisons to fellow foursome SISTAR because most of their recent material have been sexy midtempos. However, SISTAR does not have a monopoly on the sexy and mature concept. As many netizens have noted, Girls Day channel more Park Ji Yoon circa the 90s rather than SISTAR's often reclined and copied "Alone". Why can't we just commend the girls on a comeback well done?
