The Shield on FX..(nsfw)

I have never watched this show and don't plan on doing so, but I have seen the around 500+ previews for the January season premiere episodes. There are two songs in these previews, one is a rap song, and the other is a country sounding song with flashes of the show going on. Does anyone know what song this is, its really bugging me.

speaking of country, heres a country gal whom i enjoy lookin at..

It's Johnny Cash's cover of Nine Inch Nails' "Hurt."

You are missing out by not watching. The Shield is pure awesome.

It's one of the best shows on TV. It's not some cookie-cutter show like, um, everything on network TV; the cops get into some deep [censored] sometimes. In season 2 they hijacked a bunch of Armenian drug money and kept it for themselves. It's a great show because even though they break the law so much, they're always trying to do the right thing; Vic's got autistic kids and needs money to pay for their care, his marriage is failing...it's just a really gritty and captivating story.

FX comes up w/ some quality shows imo, im a nip/tuck man myself, i think i might get the shield on dvd and see whats up now.....
