Respectfully, all your taste is in your mouth. If Ray Charles, Joe Cocker and Michael MacDonald can't sing, then you might be right. However, all those artists had phenomenal careers and are considered "classic" artists. Taylor is amazingly talented.
BTW, how well would you sing with strep throat? I had to do it once and I was barely able to croak out the song. Given the circumstances, Taylor did very well.
Actually, I have had years of musical training. Taylor can't sing, neither can he dance (they even cut him up for his "dancing" after several of his performances) and had a bad night every night, not just last night.
The only thing distinctive about Taylor's voice is that he can't sing. Each of the three men you named individually, had more talent in their pinkies than Taylor has in his entire body. The guy stinks and is in way over his head.
