The talk I remember was very carefully worded to not open any critism or legal issues. They said: "some of you, even in bethel, listen to music from bands with names that contain guns or dead. Is this Christian?"
Meanwhile gay bland singers were OK.
Since then they used Eternal Flame (if I remember the name right).
Grateful dead made folky songs, I have baited witnesses with their benign sounding music more than once, then tell them who. Others are very good musicians ,composers and arrangers; Sting, enya, pink floyd, even Beatles.
Contrast the kingdom maladies, which if people liked were either deleted or rewritten
