Black Rose Immortal by Opeth, ok so it's very long, but it's more deserving of the ''epic'' tag than anything I can think of. And Just Like You Imagined has always struck me as epic for some reason, it really does sound like the end of the world.
Crossing genres, I'd also say Post Mortem by Mr. Lif & co, Stepfather Factory by El-P and Iron Galaxy by Cann Ox.
Off the top of my noodle, I'd have to say "Dechristianize" by Vital Remains. It's truly one of the most evil and malevolent songs I've ever listened to, ranging from the most brutal anti-christian epithets to just plain, outright hatred in general. A true anthem for the ungodly. It tops out at 8 min 45 seconds.
Bohemian Rhapsody probably defines the concept.
Paranoid Android by Radiohead; Third Eye by Tool; Aenema by Tool; Eulogy by Tool (pretty much anything by Tool actually); many Opeth songs; many Devin Townshend songs.
Special mention for He's Simple, He's Dumb, He's the Pilot by Grandaddy- unbelievable.
Probably most epic song, I think, is The Moor by Opeth.

FNM's "EPIC" (Live 92 versions) aren't mistitled either....
My brother was obsessed with that song when he was 3 years old 😂
I'd say anything by Tool (with a special nod to The Grudge from me) or Opeth, really...Paranoid Android by Radiohead....few others that aren't coming to mind at the moment. Damn.
