T-Pain’s fingerprints are all over pop and R&B and hip-hop. He wasn’t the first musician to use Auto-Tune as an instrument — he noticed it on a Jennifer Lopez remix, and remembers “Deep” well — but it was, as he says, his style. For a while, in the mid-2000s, he lived at the top of the charts. He dominated that brief moment of our lives when ringtones were a thing. He was celebrated as an innovator, and he happily took his talents where he was invited, which was everywhere.
