For those that haven't heard the songs yet here is a link with all of the tracks from their mini album "Sexy Beat" including their mv for "Smoky Girl"

I actually had to google to check that they had spelt smoky properly, I still spell it smokey, which according to people on some sites is "old fashioned". I like extra letters in words, it looks more complete and it's what I'm used to in general. Except apparently when I use spelt instead of spelled. Yes, I apparently write like someone from an older generation.
Song wise I actually like their song quite a bit, it catches my attention while some of their other stuff has unfortunately not been as memorable. Hoping for some cool stage performances from them.
From the rest of their mini album I guess "R U Okay" is the strongest in my opinion but I'll probably have to listen to them all at least one more time. Other than that, except for their spelling which is really just a pet peeve of mine, nothing has stood out too much.
