Kinki kids
I first heard about kinki kids when kame & yamapi covered bonnie butterfly in one of shounen club episodes during their junior days.the song is really addictive. Both koichi and tsuyoshi have great vocal too. Since then I've started to listen to kinki kids songs, but not really being updated with their new releases or schedules. A casual listener is the correct term to describe myself I suppose. A few favourite of mine include ai no katamari, flower, garasu no shounen, harmony of december. I think yamada did justice for his cover of ai no katamari as his voice brought a more heartaching feels to the song. Well, I just love his voice colour too
