As much as i love edge, i do think his voice is better suited to backing vocals. he is good - but hes not bono. and i think bonos voice has actually got better these past few years, a bit more raw. whenever you hear bono and edge singing together bono does tend to sing right over edge... bono just puts his heart and soul into a song and it realy shows. i love edge, but bono should stick to the mike thats for sure!
