2 guys committed suicide together, I believe around the late 80s. They were good friends and both Judas Priest fans. Some individuals got the idea that they got the idea to take their lives from listening to JP. It's a preposterous idea, but there it was. Rob Halford pointed out and rightly so, that a band is a business and the fans are the customers. What business wants its customers dead? They'd be out of business! That's not exactly how he worded it, but that's the gyst of what he said. Not only that, but a lot of metal bands, including JP, have gotten to know some of their fans personally. They want their friends dead? I don't think so. I am not all that familiar with JP, but I have never heard any songs by them that made me feel suicidal.
There was also a song by Ozzy called "Suicide Solution" which is about a friend of Ozzy's who took his own life. The point of the song is that suicide is NOT the solution to your problems. However, there were of course, people who gave him a lot of heat over the song claiming that it had the opposite meaning. It's about time people grew up and stopped blaming everyone and everything for things that are not the fault of some band, electronic device, etc.
