Apparently, they've never been D-NA to start with, so I'm calling them The Boss from now on.
I re-iterate what I said earlier this year (like in a lot of what I've been writing lately) - 비틀비틀 is generic, cheesy at certain points, and you know not a lot of money was invested in to this, but it's like that to show how much more talent The Boss have compared to your run-of-the-mill boyband from a small agency no one's heard of.
I'd say they're tied with BEAST - BEAST have the backing of a semi-major agency, but lack in terms of talent when compared to The Boss. Put these two groups together and you have just a little less than what DBSK had when they were just starting out.
Let us now take the time to worship Mika and Karam's vocals. I have an unpublished, unfinished, draft of a vocal commentary for The Boss (that I wrote last summer), and I call Mika the Junsu of The Boss, and Karam and Jaejoong. Their vocals are drop-dead gorgeous, and I think being in one of the many generations of Xing helped. The other three are strong too, but Karam and Mika carry the band vocally, and for a band as new as them to be as good as they are is a hard feat to even try reaching.
비틀비틀 is catchy verging on cheap sometimes, but the way all five of them carry it both live, with their stage presence, and recorded with the epic, amazing vocals give it another dimension. To be honest with you, if k-pop gave me the same songs it did this year, only with people who could actually sing them, I wouldn't be complaining.
