Speed metal is more like a bluesy, more rock n' roll punk-ish sounding genre, that was pioneered by motorhead and bands like that, Metallica showed speed metal influences on their debut "Kill 'em All" I wouldn't consider this album to be speed metal. 
 I would argue that this album could be considered contemporary heavy metal, as songs can have multiple genres attached to them, not just one to describe them. I'm going add heavy metal to the genre section, if anyone disputes this just remove it and respond here to my comments.
