I can remember "Lead in the head" (Led Zeppelin). They were big against Michael Jackson, supposedly because of his disassociated standing. Congregation-wide, they bashed the album Bad because Michael Jackson had just disassociated when he wrote it. We Are the World was also trashed because it was "promoting worldly efforts at peace and prosperity". Rubbish.
The scumbag that dragged me into the cancer had numerous other picks. He hated AC/DC, Blue Oyster Cult, Black Sabbath, and Ozzy Osbourne because they were supposedly Satanic. However, he intruded with Simon & Garfunkel, Van Halen, and Journey (which I never saw a problem with--mainstream rock). He also wanted things gone by Culture Club because Boy George took horse when he wrote the albums. And, any song that even hinted at immorality (as they define it) was "bad"--even if the logic was pure rubbish.
Now that I am no longer abiding by the witlesses, I found out that heavy metal isn't all that bad. Even before I became a witless, I had more mainstream music tastes. But, I found out that many of those hard rock and heavy metal songs of the 1970s and 1980s, and rap of the 1990s and 2000s, are better than the lame excuses of "music" they let you listen to. And better than the rubbish that passes as "music" on lamestream radio these days.
