Chris Willman Music Writer“We Don’t Talk About Bruno,” the surprise hit off the “Encanto” soundtrack, has gone where even “Let It Go” couldn’t: It’s become the first song from a Disney movie to reach No. 1 on the Billboard Hot 100 chart since “A Whole New World” from “Aladdin” did it in 1993.It joins the “Encanto” album itself as a chart-topper, as the animated film’s soundtrack remains atop the Billboard 200 chart for the third time in the last four weeks.Some other stats Billboard points out: “Bruno,” solely penned by Lin-Manuel Miranda, becomes the first Hot 100 chart-topper to have been written by a solo writer in more than four years, Ed Sheeran’s “Perfect” having been the last. It’s the first time a Miranda tune has topped the chart.
