I'm certain any one of us could do better list than this while passed out drunk on the shitter. Adam Lambert? Who the [uck fay] are Jesse McCartney or Chase Nelson even? Please help these people. I'm going to start by simply asking if these people lent money to Freddie Mercury and he didn't pay them back before tapping out of this world or he ran over their puppy. I can't think of any other reason for the omission.
Bob Dylan shouldn't be anywhere near that list. Great singer songwriter, one of the best of all time. But pure singer?
A list of pure singers that ignores 80s metal is not a valid list. Right off the top of my head....Bruce Dickinson. Then old school soul guys like Sam Cooke and Sam and Dave. I'm sure I could think of more but it's a waste of energy at this point. That list sucks.
