I don't know a man who don't like rock. Billions of people around the world who loves rock music can't be wrong. So either madtech is a girl or he is chakka or is a real paakhe. As far as Usher, his voice is like chakka's as well. Girlish voice and don't like his music and am definitely not his fan but won't say he produces bad music. After all music is music either metal or bhajan or classical music. Only those who knows how to play musical instruments know what it takes to compose music.
