1. Originally, these were going to be all really famous guys. But instead, I threw in a few non-ringers, guys who are less famous if not non-famous just for the sake of variety. However, it was hard: everyone can identify well-known crap singers (it's impossible to not know about Billy Joel, for example, no matter how much you might try and avoid him), but lesser-known crap singers are easy enough to simply not listen to, so it's harder to remember the people you don't like if they aren't accompanied by media hype and overexposure. So, apologies in advance for the relative predictability of these choices.
2. I've tried for a certain degree of variety in time, style, and offensiveness, but all of these people ruined, or at least tried to ruin, major genres of music that I, as a rule, enjoy. They've all produced music that I do not like listening to, and they've all additionally behaved in ways that have irritated me. I've mixed them up so you get people who are just now starting on their long career journeys of producing shitty music, and people who have been producing shitty music for as long as five decades.
3. I welcome your comments but not your abuse. Fuck all haters of my hate.
