Your ears & eyes are gates to your spirit. Be careful what you allow to enter through those gates. Be careful of the lyrics that you are meditating upon. Be careful of the fruit that you are eating. A major way the enemy infiltrates the mind is through music. Lean on Holy Spirit to guide you with the entertainment you are watching and the music you are listening to.
We must put on the WHOLE ARMOR of God and stand firm against the schemes of the enemy.
