Stepping outside your lane isn't always a bad thing, you know?
Here are the some of the times an artist jumped genre to guest star on a song and absolutely smashed it.
ALL TIME LOW FT. TEGAN & SARA - 'GROUND CONTROL'
What do you get when you cross one of the biggest rock bands in the world with one of the biggest duos in pop? This slow burning epic, that's what.
YOU ME AT SIX FT. WINSTON MCCALL - 'TIME IS MONEY'
You Me At Six love bringing in someone to add a little bit of grit to their songs. They've borrowed the expertise of The Blackout's Sean Smith and Bring Me The Horizon's Oli Sykes in the past. Yet it's this cut featuring the Parkway Drive frontman that really hits the spot.
FALL OUT BOY FT. EVERYONE
Fall Out Boy love a guest spot. Be it one of the most distinct voices in rap or the best songwriter of the past 50 years, no genre is too far-fetched. Look at them all!
DEMI LOVATO - 'IRRESISTIBLE'
ELTON JOHN - 'SAVE ROCK AND ROLL'
BIG SEAN - 'THE MIGHTY FALL'
FOXES - 'JUST ONE YESTERDAY'
WYCLEF JEAN - 'DEAR FUTURE SELF (HANDS UP)'
MY CHEMICAL ROMANCE FT. LIZA MINNELLI - 'MAMA'
Though she only sings one line, 'Mama' wouldn't be the same without the haunting vocals of Liza Minnelli clashing with Gerard Way before all hell breaks loose.
BRING ME THE HORIZON FT. LIGHTS - 'DON'T GO'
When Bring Me The Horizon are at both their most atmospheric and brutal, who better to add an extra layer of heartbreak than the wonderful Lights?
BRING ME THE HORIZON FT. GRIMES - 'NIHILIST BLUES'
And another one for Bring Me, who really pushed the limits of what's possible with 'amo'.
EVERY TIME I DIE FT. BRENDON URIE - 'IT REMEMBERS'
One of the most unlikely but also perfectly suited combinations that has ever been conceived. Brendon + riffs = one big fire emoji.
YUNGBLUD + TRAVIS BARKER + MACHINE GUN KELLY - 'I THINK I'M OKAY'
Possibly one of the best collaborations to come out of 2019 - this one saw Rock Sound cover stars Yungblud and Travis Barker team up with Machine Gun Kelly for this absolute BANGER.
ICE NINE KILLS FT. SAM KUBRICK - 'ENJOY YOUR SLAY'
This isn't just genre-crossing, it actually crosses medium as well. The Sam Kubrick in question who features on this tribute to The Shining is the grandson of famed director Stanley Kubrick. Because why not?!
