You know T-Pain because he made an insane amount of hits, but you also know him because he helped popularize Auto-Tune -- something he doesn't actually need, as it turns out.

Last year, he shocked a ton of people by belting out his hits without any tech help. But if he still had any doubters, he just silenced them all by sangin’ the national anthem ahead of the Dodgers/Giants game in L.A. Monday (Aug. 31).
