why do dudes sound like they're about to burst into tears whenever they sing?

You can't use Sam Smith to rep all dudes. He's especially maudlin.

Maybe it helps to show their sensitive side and sells more

'cause they're singing an emotional song? I don't know. xp
I think it depends on the genre. 🤔
I can think of a few (non pop artists) that don't sound that way.

Probably drawing upon memories
