When he's not tearing up stages the world over with A Day To Remember, frontman Jeremy McKinnon somehow finds the time to produce hits with a whole bunch of other bands. Busy guy.
In a week where his latest production effort - Wage War's 'Deadweight' - is released, here are our picks of the best songs he's had a hand in.
WAGE WAR - 'STITCH'
Jeremy's most recent collaboration, where he's helped Wage War return with an absolute monster of a second album in the form of 'Deadweight', which is out this week via Fearless Records. And it was always going to be a total winner with this as the lead single, wasn't it?
NECK DEEP - 'KALI MA'
Neck Deep were always great, but their decision to team up with Jeremy on second album 'Life's Not Out To Get You' was a match made in heaven. Mr McKinnon even pops up for a guest vocal on this one.
THE GHOST INSIDE - 'ENGINE 45'
Maybe Jeremy's heaviest venture to date. The Ghost Inside stepped up as major league heavyweights on 2012's brilliant 'Get What You Give'. This, the stand-out track, became an instant classic for beatdown junkies everywhere. Like a freight train? You better believe it.
A DAY TO REMEMBER - 'ALL I WANT'
He may be in the band, but we couldn't leave this out, could we? Turning his hand to the A Day To Remember production desk for the first time on the band's 2010 chorus-fest 'What Separates Me From You', the band came back with one of their biggest hits. A bona fide classic.
THE DEVIL WEARS PRADA - 'MAMMOTH'
Testing the waters of his collaboration talents, Jeremy lent additional vocal production to the band's 2011 album 'Dead Throne'. The result? It saw them step up from Warped Tour youngsters into straight-up heavy titans.
NECK DEEP - 'CAN'T KICK UP THE ROOTS'
Still one of the biggest and best Neck Deep songs to date, Jeremy played a part in creating this classic summer anthem - providing a watershed moment for the band. Not bad, eh?
A DAY TO REMEMBER - 'END OF ME'
He may have pop-punk and metalcore nailed, but Jeremy's always had an ear for a ballad, too. So on 2013's triumphant 'Common Courtesy', he turned that dial right up to 1,000 on this 10/10 slow jam.
WAGE WAR - 'THE RIVER'
Clearly a man with an eye and ear for talent, Jeremy has been helping Wage War write mosh anthems since (almost) the very beginning. Been wondering why the band have become stars of the Warped Tour scene in recent years? Here's another reason why.
THE GHOST INSIDE - 'MOVE ME'
Teaming up with the band once again for 2014's 'Dear Youth', Jeremy helped The Ghost Inside up their game even further, and 'Move Me' is a perfect example. Still heavy as a tonne of bricks but incorporating huge choruses into the mix too ("BRICK BY BRICK BY BRICKKKKK"), together they created a mosh masterpiece.
A DAY TO REMEMBER - 'RIGHT BACK AT IT AGAIN'
We had to finish on a big one, didn't we? 'Right Back At It Again' encapsulates everything great about A Day To Remember. Massive chorus? Check. Savage mosh call? Check. Tonnes of bounce? Check. It acts as a prime example of why the band, and Jeremy himself, are such an asset to our world.
