"Rappa Ternt Singa" T-Pain became a global sensation for his clever use of auto-tune and caused a seismic shift in music as EVERYONE used his sound to the point of no return. Now that the "autotune" era has seemingly went away, T-Pain, while continuing to use autotune in some of latest material, has gone on to showcase his real voice in a series of shows and videos over the last few years. He recently performed on NPR's "Front Row Concert" to perform a cover of Sam Cooke's immortal signature song "A Change Is Gonna Come".
