I sorta stopped listening to anything that glorifies drugs, sex, rebellion. Or bands that are darker. Radiohead, pink Floyd, certain albums by The Who. The sex pistols. Nirvana.
My two fav Who cds, i quit listening to. Both glorify sin! But theres still much secular music that i find Jesus would not mind. Most peter gabriel, one hit wonders from the 70s. I love musicals. Pete Townshend solo, The Clash. Im older so...I just gave up things that i felt Jesus would not approve. This includes comedians George Carlin, bill hicks and southpark. Have you stopped listening to anything?
Pastor Bob Beeman is a great hard rocker, yet a wonderful Christian teacher. He has long hair and is totally metal. Hes very open-minded and shares the gospel well! Youtube for some interesting teaching about controversial subjects. He often answers questions about music. God Bless You!;)
