"When some ugly thought from the nether kingdom tries to get into my mind, I move it out with good music, hymns. That is one of the reasons why you are very, very, very, very, very, very foolish when you like to participate in music that is dark and noisy. Worthy inspiration cannot get through to you where you are. No matter how popular it may be or how much you want to belong, just remember that there are those angels of the devil using you."
-Elder Boyd K. Packer
