Which widely regarded musical genius do you hate and why?

Every single pop artist. Every one. Because the music is trash, it is almost always generated by a computer, half of em dont even write the songs, and when they do they are songs built just to sound catchy so it gets stuck in your head. A lot of money and research went into figuring out how to do that. Just like any established product, you will try to find ways to cut corners, use cheaper and flimsier components, outsource the work to cheaper labor, etc to get the price low and maximize profits. That is exactly what you are seeing with modern pop music.
