On the seven-year anniversary of Zedd's "Clarity," which was co-written by Porter Robinson, Skylar Grey and Matthew Koma, Zedd publicly celebrated what became his first Hot 100 hit, writing, "SPECTRUM CAME OUT 7 YEARS AGO AND CHANGED MY LIFE FOREVER."
In response, Koma took to social media, denouncing his former collaborator as "toxic" and "self-serving" in a long Instagram post. "It’s a really sad truth because I’m extremely proud of the work he and I did together,” Koma wrote. “Unfortunately, my good feelings toward these songs have all but disappeared.”
Koma said he met Zedd their label Interscope to work on what would become Zedd's hits "Clarity" and "Spectrum." He claimed Zedd suffered from an obvious "inferiority complex" and took small "blows" at him in interviews, apparently saying he'd written Koma's lyrics and refusing to pay him for recorded vocals. Koma also said he shared a song called "Suitcase" with the producer, and when Zedd allegedly demanded the right to release the song under his own name with a different singer, Koma refused, released the song on his own four years later.
Koma continued that he was not invited to the "Clarity" Grammy ceremony (the song won best dance recording in 2014), that he was "brushed under the rug" in a documentary called The Making of Zedd (traces of which Billboard can not immediately find online. A documentary called "Moment of Clarity" posted to Zedd's YouTube does feature a clip of Zedd thanking "Matthew Koma who wrote this song with me" in his Grammy speech.) Koma also claimed Zedd "could only play the piano in the key of C" and that Zedd no longer produces his own songs.
Zedd affirmed that he's given Koma songwriting credit for top lines and mentioned his name in videos. He alos broke down his side of the story for "Clarity," "Spectrum," "Find You" and "Suitcase." He said accusations that he's "the worst" and no longer produces his own material are "obviously not true."
"Nothing will ever change how proud I am of the songs I made with Matt," Zedd wrote. "They will forever be part of our history and even through it’s hard to sit through a personal track like this, I still love the songs just as much and I still think Matt is one of the best songwriters I’ve ever gotten to work with."
