One year ago today, One Direction announced the details of their album Four, including the 24-hour-only download of a new song called "Fireproof." And because Directioners never miss an anniversary, #1YearSinceFireproof started trending on Twitter on Tuesday. Fans were full of fond reminiscences.

Well, mostly fond.

As much as One Direction are a pop band, they've relied on rock-oriented sounds throughout their career to make their songs as epic and bombastic as possible. 2013's Midnight Memories had a ton of '80s hair metal influence (as we've pointed out before) and Four continued the classic-rock trend on songs like "Where Do Broken Hearts Go" and "Steal My Girl."

But there's nothing like an old-fashioned, hands in the dirt, rockin' cover of a 1D tune to appreciate how massive the songs always sound, no matter what genre they're performed in. Here are a few of our favorites.

Mitski - "Fireproof"

A top contender for best 1D cover on the planet.

Wolf Alice - "Steal My Girl"

Trippier than Directioners are used to, but the sentiment is still there.

The Vamps - "Best Song Ever"

Spot on, fellas. Spot on.

The Vaccines - "Night Changes"

Morphed into a sparkly pop-rock hit complete with a key change!

Shawn Mendes - "Drag Me Down"

Listen to the FORCE of those strums.

Lissie - "Story Of My Life"

Ragged, soulful and skeletal. And full of pure power.

Postmodern Jukebox ft. Jeffrey James - "Steal My Girl"

It swings. It shimmies. It rocks, in a '50s kinda way.

So, about that fifth album...
