Yes, it's Something by Girls Day. I couldn't get it embed properly it seems . I fixed the link, I hope it links you to the correct destination now
Youtube Canada recognizes your link!
Loved it, a perfect flowing blend of lyrics into the music. I don't know Korean but that didn't stop me enjoying the song at all (The pain of non translated music! and having a station that pre translates all words before playing any Korean video! Curse you KMTV!)
A bit of help to embed the video right onto these pages (Up to 10 or 12 , forget which!) don't post the link youtube gives you from the share buttom, instead go to Youtube browser and copy it onto these pages. In preview it will always shows but one you hit the limit only the kink will appear. You can check out my music topic "From The Turntales In my Mind to get a better understanding of what I'm trying to say!
Oh and merit for introducing me to Girls Day, will be listening to more when i find them!
