Blood To call it a certain genre it needs to be written in the actual writing of their review not just a tag that says Genre XXXX Those are never reliable and thats why we dont use AllMusic unless its written in the review above their track listing I would also advise you to please stop trying to find sources for alternative metal as Im pretty sure no sources fit these described criteria for Blood If no reviewers call it alternative metal reliably then Wikipedia cant either The source you gave for the genres however does support metalcore with the quote you gave Per WPRS anything likely to be challenged or challenged already must be backed up and alternative metal has been challenged for accuracy Some of us me definitely among them dont for a second believe Blood is alternative metal So basically we can use our opinions to remove uncited material but not the reverse Hope I clarified things
