Parodies as Guides

While tumbling down a Rosalía wormhole recently (I highly recommend it), I came across a stunningly sharp insight, from a long video about her masterpiece El Mal Quererby Jaime Altozano (you can turn on English subtitles). He's talking about elements of trap and he goes on a tangent to say:

My advice: If you want to know the stereotypes in a genre, go to the parodies. Because parodies cannot risk innovation. If Young Beef makes a trap song that’s not clear whether it is or isn’t trap, he’s enlarging the concept of trap. But if a parody makes something that’s not clear whether it is or isn’t trap, it’s failing as a parody. So parodies are usually wonderful lists of the components of a genre.
