its really uncommon for people to sing with the melodic version of their proper singing voice.
I lived in UK & Australia and Australians don't seem to know what to do, emulating British singers and Americans and especially Aussie hiphop is a laugh as the accent *really* doesn't work IMHO
UK rappers of course use real accents presuming they are from London,most of the folk genre my S.O. listens to put on heavy affectation where you would never be able to match the person with the singing from just hearing them speak.
basically accents and affectations are part of musical genres even when people find it cringe, we'd have to knock vast swathes of people to show proper objection to less than authentic singing voices - I mean, think of Brian Harvey in the 90s, rated at the time (he wrecked it now) as having a strong and unique voice, it got him promoted in East 17 from rando schoolmate backup dancer to lead vocalist and he was putting on an American R&B singers voice despite his thick east london accent when speaking..
even Wyclef Jean thought he was talking to a black guy when he listened to the recordings that led to their collaboration football song around 2001.
it is what it is.
I give the kid a lot of rope considering who his mother is.
Peter was the opening act for a buddy in the early 90s and they loved having him round for comic relief, very nice guy, very vapid, would be chatting and then scope that female dancers or other attractive women were entering the area and the shirt is off and he has unceremoniously dropped to the floor for 100 situps
he seems like a sweet enough Mimbo
