A few days ago, seven member boy group U-Kiss released a new version of their current promotional track, What. The boys and the producers proved that is was possible to make the already infectious track even more addicting. http://www.youtube.com/watch?v=VAkt_FcvrLY As the boys took the stage today, it seems as though their energy shot through the roof along with the high energy the song already displays. So did you guys think the upgraded version of their song was worth the time, or do you happen to prefer the older version? Check their performance out below and tell us what you think! http://www.youtube.com/watch?v=tCJO6zfH4Cg
