By now, you probably already know Microsoft Forms, the form./quiz feature from Office 365.
Since its introduction, Forms has evolved to provide more capabilities, including more customization options.
Well, you can now also add background music to entertain users when filling up your form.
To do so, just create or edit a Forms (https://forms.office.com/) and edit the Theme to turn on the Background music option.
While editing the form, you can hear the background music you have selected to choose if this is the one you want to use.
