From Vlad TV:
T-Pain clarified statements about Future not using auto-tune correctly, explaining that no other artist out right now knows the technology better than himself. He then begins to explain the history of why auto-tune was invented, which came from knowledge straight from the creator, whom he also met.
T-Pain also speaks about working with Kanye on “808’s & Heartbreaks’ in Hawaii, but admits he was upset over all the praise that Kanye got, because he felt that “Rapper Turned Singer” was the same album. When asked about working on Kanye’s “Good Life” track, T-Pain admits that it was one of the hardest songs he’s ever worked on.
