kurt cobain's delivery was fantastic and engaging, he wasn't the best note hitter, didn't have the best vocal range and didn't annunciation his words but none of that actually matters. his singing is the reason people think he's a good lyricist and i don't mean because of the lack of annunciation, inane BS sounds deep coming from him.
bon jovi's delivery is cheesy and dated, he is a good note hitter, he does have vocal range, but none of that actually matters. his singing is the reason people think he's an unsophisticated lyricist. it is the reason no one remembers a single bon jovi lyric that wasn't part of a chorus.
