Although I enjoy Wham's and GreySynth's analysis, there is a crucial point which you haven't really touched. That is the breathing, pronounciation and rhythm problems. And although it is kinda dumb, I can neglect bad pronounciation. However bad rhythm is a really off-putting charcteristic. And bad breathing i.e. the incapability to sing a continious note/melody for its proper duration is also quite a bummer.

Rhythm : I mean, there is no point in singing bad medicine when you are off rhyhtm, ansd similarly for the other uptempo stuff. Yes the singer is not the drummer nor the bassist, but his lines should underline the groove, rather than undermining it.


woow cool pun there.

" yo I'm Jon, I be called the underminer
was a time when I be da underliner
but times change, it's not all the same
still I play da million-face-rockin' game "
