I was a teenager back during the big backward masking panic of the seventies. But that alone didn't warrant the stamp of disapproval. Drugs, sex, hell, long hair was enough to have parents and elders be prejudices against certain music and bands.
Albums that I disposed of (that I remember anyway):
Led Zeppelin (supposed backward masking...and Stairway was supposedly written with demon help)
KISS (K.inghts I.n S.atan's S.ervice need I say more?)
The Stones (Her Satanic Majesty Requests..I didn't own that album, but when my parents saw that one existed, all others fell under the sword)
The Eagles (Just Hotel California...the picture of the character over the balcony was rumored to be a Satan worshipper and the song HC was demonic)
Fleetwood Mac (my parents saw the crystal ball on the album covers and out they went)
Queen (backward masking again...and they were gay)
Rush (R.aised U.nder S.atan's H.ouse...and some of the albums had pentagrams on them)
Music that I was counseled to get rid of, but somehow rationalized that they didn't need throwing away:
The Beatles (drugs, sex, they were the leaders of the downfall of youth and they played the sitar for God's sake )
James Taylor (he spent time in a mental instituition...he's probably demon influenced. Again)
Cream (too psychedelic...and just look at them...disgraceful. And yet again)
Hendrix (drugs, and you call that guitar playing? that's just noise...disgusting. One last time)
I too replaced most of the ones I threw away...and most it was I while I was still a JW. I got older and realized that it was a stupid witch hunt to begin with.
But the older I get, the more diverse my music selections gets. I'm all over the place now...and I've gotten to where I prefer live music over anything. I go to local clubs to find new music and I download live shows off the Internet and listen to them.
