Genre Motif/Rock

Rock used to be rebellious, but that aspect has become more of a joke over time. As Lisa Simpson put it (albeit not about Rock), "that's rebellious... in a conformist sort of way". Indeed, Rock is embraced by such a wide variety of people that really, it's only ever used very generically. Rock has become sort of a mythical entity as well, with The Power of Rock based on this. All you need to cause radical social change is a guitar, bassist, and drummer to rock out. The ubiquitous nature of Rock has made it more of a Dead Horse Trope than anything at this point.

Examples:
 * In the first Kill Bill film, a Japanese Rockabilly-style band got a showcase. It was meant as a bit of a Soundtrack Dissonance moment, where something that was so American in nature gets used in a Japanese setting.
 * Badbutt characters in general will have rock music accompanying their appearances every now and then. Some examples include Sonic the Hedgehog and Rainbow Dash from My Little Pony Friendship Is Magic.
