I've just asked an LLM whether Doo-Wap is Rock n Roll or Pop and it came back with this...
Doo-wop is best described as a genre that exists at the intersection of rock and roll and pop. Its rhythmic foundation aligns it with rock and roll, while its melodic and harmonic sensibilities make it a precursor to modern pop music. Some songs lean more towards one category than the other, depending on their style and audience.
We could have just told everyone to look up the genres on ChatGPT , though it wouldn't have been as much fun!
