Woah! That is almost blasphemous to say about the man in black. It's not only his singing that makes him great, it's everything about him. The man is a legend. He commands respect.
I once saw Henry Rollins on his speaking tour and he told a story of when him, Joe Strummer, and Tom Petty all went to see Johnny Cash and they were all completely star-struck! These guys were all close to legends in their own right. I thought it was pretty cool to hear how these guys felt about seeing Johnny Cash.
Speaking of legends that fall short in our eyes, What's up with Merle Haggard hooking up and doing songs with Gretchen Wilson. I am having a really hard time listening to him anymore knowing he has stooped to that!
By the way, I will always love to listen to Whiskey River and Luchenbach Texas, So I don't hate all of his stuff, just the stuff that paved the way for all the crap we hear on today's radio. And as for georgia and Crazy, Ray Charles and Patsy Cline did them better.
