When we used to put together these kinds of round-ups, we'd always have to put in effort to make sure it's a well-rounded list in terms of genres and styles each month. These days, we don't even have to try. Music is so all-over-the-place today that it would be impossible to make a list that isn't diverse.
This month's roster of Best New Artists is a sign of the times, and a sign of where things are going in 2020 and beyond. There is no "next big thing" in music, because what's next is everything all at once.
