I can't recall if it was a kpop video or jpop (but I'm learning toward kpop), but it started off with a girl being put together/built, like she was a cyborg or android of some sort. It's NOT the money song by Wonder Girls; in fact, watching that video is what prompted the memory. I saw it a few months ago; I think it was fairly new, or at least from the past couple of years. IIRC, the music was pop/dancey, and I'm pretty sure it was a solo artist, tho I think she had back-up dancers so it *could* have been a girl group (but I'm thinking solo artist).
It was sung by a girl.
THIS IS DRIVING ME SO CRAZY. I can't even explain the amount of searching I've been doing, I am truly obsessed with finding this out.
