siri rap is an underground hip-hop subgenre often with elements of hyperpop. it originates as a joke on stan twitter and is mostly made ironically, but i think it should be a genre because it doesn't really fit anything else...

basically, siri rap is hip-hop music made with an artificial voice generator. the main element that makes it considered "siri rap" is that it uses a voice generator like siri, not a real voice.

you can see in the tag some examples of siri rap artists.
