Paul in Eph. 2:2 :

"In which you once walked according to the course of this world, according to the prince of the power of the air the spirit who now works in the sons of disobedience."

See also 1John 4:4, 1Pet. 5:8-9, etc. The [underlined] phrase above indicates that Satan influences what we hear from the air -- What is broadcast over the radio, tv and movies, whether spoken, sung. or suggested.
