In what way are you distorting the interface in this task?
Are you referring to media already placed on the Timeline being disturbed when you drag a file to the Timeline from Project Assets? Or, maybe audio file already on the Timeline breaking up when you drag a file from Project Assets to the Timeline?
If so, please hold down the Alt key of the computer main keyboard as you drag the file in place on the Timeline.
If other than the above, please supply additional information for us to help you.
