Soribada just tweeted something about W&Whale so I just had to follow that link. Turns out they released a digital funk rock single by the name of Born To Rock today, August 31. Seems they have somehow worked together with GAP on this one. If you’re on a Windows computer you can sample a minute of the song here.
Update (090901): wassereis has found the music video at Cyworld.
there’s a video to this at cyworld
Thank you ^^
