Genre is subjective to a point though, like people including the artists will argue about what genre something is and there will be no consensus or any authority that says "it's this genre". It gets more complicated when genres get mixed. like djazz, which is a mix of djent and jazz, where djent is an offshoot of progressive metal named by Meshuggah but most djent is very dissimilar to Meshuggah so Meshuggah itself doesn't fit the djent mold.
