I had no idea that Matthew Koma and Zedd had any sort of issues. That is until about 24 hours ago when Matthew broke his silence on how things went down between him and the dj/producer. Together they have come up with some really great tracks (whether it be writing or vocals) like "Spectrum" and "Clarity" to name a few. From what I gather from Matthew's Twitter he has been getting the short end of the stick for quite some time and is not happy about it.
