In reply to flopsicle:
Freddie Mercury is hard to beat. Range, delivery, tenderness, originality - He was so on it. Classical -wise - Jussi Bjorling had a remarkable voice
In the age of X-factor where so many can hit the right notes with perfect intonation, & perfect vibrato, few performances are genuinely moving.
Hitting the right notes with a hint of personality thrown in is the realm of karaoke. Apologies to those who have given the thumbs-up to Rod Stewart & Tom Jones, but for me, these guys are simply very very good Karaoke singers - not great singers. Their shoes could have been filled by any one of a thousand others who didn't get the break.
The art & skill of being a great singer is surely about far more than hitting the notes. What about these guys? some of the most moving performers ever, and they all had a 'crap' voice.
