Music bible Billboard has sparked outrage in the music industry by sending a sexual harassment questionnaire to top female execs ahead of its Women in Music issue.

Sources say the power women at labels including Atlantic, Universal, Epic and Sony were sent the survey for the mag’s Nov. 28 issue with questions including: “Have you ever witnessed or been made aware of the sexual harassment or assault of a colleague?” and “Have you ever been the subject of sexual harassment?”

The survey also included, “If your answer to Question No. 3 is yes, were you harassed by a . . . ” with a drop-down menu of choices. And “If you answered yes to Question No. 3, were you harassed in . . . ” with more choices.

A music industry vet told Page Six, “All the female execs are furious about this — as if they are going to answer such personal questions like it was a multiple-choice test?” The source added, “Perhaps Billboard should have sent it to its staff first?”

The Post reported this month that Billboard chief strategy officer Stephen Blackwell resigned after a former intern accused him of sexual harassment at a previous job he held years ago.

It’s not the first time Billboard’s gotten into hot water with industry pros over insensitive questions. In 2015, it circulated a poll to readers with questions including: “Who do you believe: (i) Kesha (ii) Dr. Luke,” a reference to singer Kesha’s allegation of sexual abuse by the producer.

A rep told us: “In an effort to address the sexual-harassment crisis sweeping through the entertainment industry, Billboard encouraged all levels of female executives involved in our Women in Music issue to participate in a confidential and optional survey. As the world’s largest voice in music, our goal was to better assess the prevalence of sexual misconduct within the music industry. As we develop more shared knowledge around this issue, we can better confront it and hopefully prevent negative experiences from happening in the future.”

Billboard hosts its Women in Music awards Nov. 30 in LA, which will honor artists including Selena Gomez and Kelly Clarkson.
