In this case, @Miss_E3 would have the weak conscience, though. That section is about not offending believers with weak consciences who think that eating meat sacrificed to idols is a sin against God. Likewise, @Miss_E3 believes that if one track by a certain artist has a lie in it, his entire catalog is contaminated.
More mature believers know that idols have no power to spiritually do anything, including affect meat. In the same way, a five-note instrumental track is just that and has no power over me, even if the guy who produced it made other music that is filled with lies.
But the fact of the matter is that young believers tend to believe more lies, and so they are more easily led astray back into the darkness. They have to avoid more lies in order to stay in the faith, and give them time to “learn to distinguish good from evil” (Hebrews). More mature believers should help them with this task, and not cause them to stumble by introducing them to things that they believe to be wrong, thus discrediting themselves.
I don’t believe that @John_Otterblast had that in mind when he started the discussion of this artist, however, and I didn’t know that @Miss_E3 would be offended by it. So we have sinned in our ignorance. I also didn’t know about the line @Miss_E3 quoted about God knowing where Avicii was going.
I’d recommend giving Tremonti a try. The tracks “Dust” and “Trust” may be closer to your vibe. Like Cobain, Mark Tremonti is extremely good at guitar, and his songs aren’t rainbows. He also has the bonus of being clean and somewhat Christian also.
