Come look at my favorite old men

James Hetfield and Ozzy Osbourne

Well, you wonder why I always dress in black

Why you never see bright colors on my back

And why does my appearance seem to have a somber tone

Well, there's a reason for the things that I have on

I wear the black for the poor and the beaten down

Livin' in the hopeless, hungry side of town

I wear it for the prisoner who has long paid for his crime

But is there because he's a victim of the times

I wear the black for those who've never read

Or listened to the words that Jesus said

About the road to happiness through love and charity

Why, you'd think He's talking straight to you and me

Well, we're doin' mighty fine, I do suppose

In our streak of lightnin' cars and fancy clothes

But just so we're reminded of the ones who are held back

Up front there ought to be a man in black

I wear it for the sick and lonely old

For the reckless ones whose bad trip left them cold

I wear the black in mournin' for the lives that could have been

Each week we lose a hundred fine young men

And I wear it for the thousands who have died

Believin' that the Lord was on their side

I wear it for another hundred-thousand who have died

Believin' that we all were on their side

Well, there's things that never will be right, I know

And things need changin' everywhere you go

But 'til we start to make a move to make a few things right

You'll never see me wear a suit of white

Ah, I'd love to wear a rainbow every day

And tell the world that everything's okay

But I'll try to carry off a little darkness on my back

'Til things are brighter, I'm the man in black

That right there is an anti-war, anti-bigot, anti-mass-incarceration, anti-war-on-drugs (Cash was an addict in various stages of recovery who was pissed as hell about how this country treats people with substance issues), eat-the-rich protest song. And it was arguably his signature song, his personal manifesto. Notice that even the Jesus reference, which today would be a signal that the song is about to drop some racist dogwhistles, segues immediately into a line about "the road to happiness through love and charity". As in "Motherfucker, our shared god said love thy neighbor and care for the poor and the outsider, and we both know he didn't fucking stutter." He's throwing shade at self-described Christians who use his religion as a cudgel to beat people with.

Johnny Cash wasn't a conservative. I'm pretty sure if he were alive and in reasonably good health today, he'd knock Jason Aldean's teeth out (or, failing that, write a song so devastatingly memetic about how much Aldean sucks that Aldean would never work in music again).
