Hip-hop superstar Jay-Z has pronounced "autotune" dead. Autotune - the vocal 'enhancer' - is a studio trick being used by rappers and R&B artists worldwide giving them a distinct electronic/warbled tone that people either love or hate. Super-rapper Jay-Z falls in the hate camp. After releasing an album buzz track called "D.O.A. (Death of Autotune)," he has decided to collaborate with other big name artists notorious for its use: Rihanna and Kanye West . In his new single, "Run This Town," all 3 artists lay down some stripped vocal lines claiming their sovereignty over Hip-Hopdom.
