Is vocal karoke permissible....?

Music is a deadly disease that has a profound effect on human heart.

أن رسول الله -صلى الله عليه وسلم- قال « فى هذه الأمة خسف ومسخ وقذف ». فقال رجل من المسلمين يا رسول الله ومتى ذاك قال « إذا ظهرت القينات والمعازف وشربت الخمور ». 
                          (جامع الترمذي)
((In this Ummah there will be [people who will be] sunk into the earth, deformed, and upon whom stones will rain from heaven.))

When the Sahâbî enquired as to when will that be, Rasûlullâh sallallâhu ‘alayhi wasallam replied:

((When singing girls and instruments of music will appear (become prevalent), and wine will be drunk.))

As listening to music is prohibited; listening to music made by vocal karaoke is also not permissible.
