I listen to a fair amount of pop music, and I have picked up on the trend of high ranges for the male pop singers (Somehow, this seems less pronounced on the female side). The male pop singers all seem to have much higher ranges than most average males (Source: People attempting pop songs). Sure, this is to be expected, as these singers are all professional singers, but it just seems to be extremely concentrated in the higher range rather than the lower end.
I've run across a few sources claiming that most pop singers sing in the tenor range. I don't doubt this, but I'm curious as to how many of them are really tenors and how many are baritones singing above their voice type's typical range. (I know, there are many definitions of the ranges of each voice type, but I don't mean the classical definitions of types). The most common voice type is baritone, but nearly all male pop songs are in a tenor range. How does that work?
Some male singers have voices that I would not really identify as tenor based on how their voices sound as though it's a struggle to hit G4, but then they hit a B4 and I don't know what they are. (In all of these cases, I've ruled out falsetto, they sound too strong).
Who on the current (maybe last 30-40 years, although anything after the Beatles will do) pop scene would you consider to be a tenor? Who as baritone extending upward? And what are your methods/processes for determining?
There are some really extreme examples (Was Prince a tenor? Freddie Mercury? Michael Jackson?), but I mostly want a general assessment of the average current male pop artist.
