Can we just all agree that RS isn't even relevant anymore? On a list of any "relevency" today, RS wouldn't even make #123. With advent of social media and other technical advances, who the heck needs RS? Just watch YouTube is you want to see how Carpenters are viewed today. In short, RS just doesn't matter.
I'm not sure to what extent any form of music press is relevant in the age of the internet and social media, nor how it's possible to rank objectively something that is subjective by definition. I agree with Ed that these rankings exist to encourage clicks, though I was perplexed that the description of a singer included in a Best of All Time list was so ungracious. As Samar says, and as we've seen so many times in the past, such comments say more about the reviewer than the artist.
