Probably the most famous twins in the world, The Madden Brothers have always kept themselves busy, both with and without Good Charlotte. Here are of their best appearances on other people's songs.
ALL TIME LOW - 'BAIL ME OUT'
All Time Low really did some experimenting with their sound on 'Future Hearts' didn't they? Here's one of poppier offerings that could very easily pass as a Good Charlotte song, featuring the enthusiastic croons of Joel.
TONIGHT ALIVE - 'BREAKDOWN'
Here we find Tonight Alive at their most emotional with Benji just adding to the intensity. Features one hell of a key change and all.
N.E.R.D - 'JUMP'
Pharrell may be one of the biggest stars in the world, but him and the rest of N.E.R.D have always been a little bit emo at heart. They even let the twins belt out a chorus and a verse on this absolute classic at the height of their success. The definition of a winning combo.
GOLDFINGER - 'JANUARY'
It's no secret that John Feldmann and the Maddens are the best of mates after working together for many, many years. Here that friendship is solidified by Joel singing along to Feldy getting sad about his girlfriend leaving him.
THREE 6 MAFIA - 'MY OWN WAY'
Rap has always played a huge influence within the Good Charlotte story, so it only makes sense that the lads would dip their toes into the culture every now and then. Here they are appearing with the hardest of the hard.
THE X-ECUTIONERS - 'LET'S GO'
The Maddens even like to immerse themselves in nu-metal from time to time you know. Here they are laying some bars on a proper industrial number.
CHAE HAWK - 'LOST'
The lads don't just stick to the gangster side of rap you know? They also like to dabble in the inspiration side of things, just like Joel did on this uplifting number by Chae Hawk.
THE 69 EYES - 'DEAD N GONE'
With the video directed by Bam Margera, this sultry rock and roll number gets some well needed grit thanks to Benji's gruff tone.
KILL HANNAH - 'SNOWBLINDED'
As tender a love song as you're gonna get, Kill Hannah felt like the best cherry to place on top of this sundae was a Benji Madden shaped one. Swoon.
