I usually find "perfect" singing voices boring as hell. I like voices with character. There are some, like Audra McDonald, that hit a wonderful balance of technical precision and real interpretive flair. But when I hear a singer who seems focused in hitting notes rather than interpreting a song/character, I just stop caring. In short, I'd rather have an interesting voice than a perfect one.
"You travel alone because other people are only there to remind you how much that hook hurts that we all bit down on. Wait for that one day we can bite free and get back out there in space where we belong, sail back over water, over skies, into space, the hook finally out of our mouths and we wander back out there in space spawning to other planets never to return hurrah to earth and we'll look back and can't even see these lives here anymore. Only the taste of blood to remind us we ever existed. The earth is small. We're gone. We're dead. We're safe."
