Well.... truthfully, I find the song over compressed which renders the dynamics (and thus auditory interest) rather flat. While Kevin is on key, the vibrato really harms the sonority as he is off key when he goes above and below the fundamental (vibrato should be a harmonic component). I suspect if I was producing this song, there might be some hard feelings as I would force take after take to get rid of it. I generally harp on (false) vibrato because it is too often used as a "search" for tone, such as here. I suspect that this is a done deal and you are not too likely to re-record the vox, but I would. This is, however, only one man's opinion.
