OK, so a post on KVR gets me looking at K-pop youtube videos and now I'm a huge BoA fan. I think I have to turn my niece on to her so I have an excuse to go to a concert. Her latest album is her US debut, I saw some posts mentioning a tour in 2010. Unfortunately much of the US debut has some pretty cliche production, autotune abounds. Her earlier stuff is better IMO, irresistably catchy. Some videos (many are in Korean or Japanese) ...
EDIT: All the videos that were originally linked in this post are now embedded in later entries.
Moto - great song and video
