Best voice in rock...

[Pilky]

Now I know this is going to stir some strong feelings but hey what the hell...
I went watching the Thunder/Whitesnake/Def Leopard gig in Liverpool the other week and recently went along to Foo's and Maiden gigs and its got me thinking.....who has the best voice in rock? Not the best song or band in general but actual singing qualities??
Some have strong distinctive, iconic voices even such as Bruce Dickinson or even Lemmy but for me Danny Bowes has the best voice...but what do you think?
