In late of 2000, for most of the perspectives about Korean waves had been moved on the 3rd stage of the K-pop industrial structure, K-pop idol stars as contents of Korean popular music have turned the pivotal co.ntents in East Asia and West countries. This research examined how Taiwan Residents K-pop consumers are identified as the K-pop enthusiast legitimizing and what they represent the ＂prosumer＂ of Korean popular music. Moreover, the practice of K-pop is getting turn consumer in Korean song karaoke （KTV） in Taipei city. What sort of cultural form emerges the political representation in the cultural space, K-pop KTV in Taipei. Through how Taiwan Residents K-pop followers diverse K-pop music for singing K-pop in KTV, it could more elaborate the meaning of contents the culture form of space between production and consumption of the cultural mediation.展开更多
