It shouldnt The album notes dont do trackbytrack credits so neither should we Just listen for yourself is original research you need to cite a source that gives these credits The infoboxes say punk rock because that is the genre that both the band themselves and secondary sources most often associate them with Regardless of what the genres are when you decide to change them but dont back up the change by citing a source or even stating a reason in your edit summary then its clear you are changing them to suit your own point of view which is not acceptable
