5. Black Sabbath - Mob Rules
https://www.youtube.com/watch?v=cATPLk559XY Appearing a handful of times across DLC and on-disc, Sabbath are one of those bands that just keep on giving, however it's when you switch gears from the Ozzy-fronted material to the late Ronnie James Dio that you open up a whole new realm of singing possibilities. Whilst the crazy bat-noshing frontman will admit himself he's not got anything close to great range or projection, Dio's pipes are of the most righteous construction - not to mention the riff that opens this track is such a simply-effective blast of old school hard rock it'll make you scream "Come on!" before the song does. Sabbath's 2013 effort 13 was just as spectacular as their older work, and it's because guys like Tony Iommi and Geezer Butler just have endless wells of secret sauce to dish out - thankfully, even when they lost such a memorable frontman, what came out the other end was just as brilliant.
