This is a tough question indeed. And sorry I didn’t answer immediately. There are so may great and talented singers. And some are popular and some are not. Donny Osmand has/had? the perfection in terms of pitch, intonation etc… for many parts. Michael Anthony and Sting are great in layers and harmonies. The Beatles as a four piece. Freddy Mecury had an absolutely amazing Tenor I/Alto voice as well as Jon Anderson of YES. Collins and Gabriel have nice dirty gravel voices that I like. And of course you know who my all time favorite singer is. No other, Howard Jones. I was attracted to his beautiful voice before I knew who he was. But there are many close behind Howard but sound very similar. Tears for fear’s Roland Orzabal, Duran Duran’s Simon LeBon, Thompsin Twins’ Tom Bailey, The Cure’s Robert Smith (somehow I like his whining), Information Society’s Kurt Larson, OMD’s Andy McCluskey, When In Rome’s Clive Farrington and Andrew Mann (whichever sings ‘The Promise’). I could go on with these 80’s icons but they are only second.
Howard Jones is my all time favorite male vocalist.
I like titties.
