The performance has divided people online. Some really appreciating the cover while others are pretty much calling it dog shit.
Post, real name Austin, decided to cover the song because his younger brother who was once a Marine loved it.
"This was on an island you could drive around in a couple of hours, and he played it. And I guess I've just been thinking about that a lot lately."
Posty also said he gets pretty emotional hearing the song because of all the memories it brings back about his little bro.
