These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Epic Riff: "The Hardest Button to Button", "Seven Nation Army", "The Air Near My Fingers", "Blue Orchid", "Dead Leaves and the Dirty Ground", "Icky Thump"... Hell, it's actually harder to find a White Stripes song that doesn't have an epic riff.
Internet Backdraft: If you want to start an epic internet throwdown, just go onto a rock music forum and write a post either defending Meg as a good drummer or attacking her as a bad one.
Also, the fact that they don't have a bassist. A ridiculous number of Internet debates have started over whether they should or should not be knee-jerk dismissed based on that alone.
