==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 that's why we don't use AllMusic unless it's written in the review above their track listing. I would also advise you to please stop trying to find sources for alternative metal, as I'm pretty sure no sources fit these described criteria for Blood. If no reviewers call it alternative metal reliably, then Wikipedia can't either. The source you gave for the genres, however, does support metalcore with the quote you gave. Per WP:RS, 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, don't 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, '''  ~talk to me!~
