I get the premise of the thread. And to be honest, OP does have a point. Negativity sells. And I think that might just be due to the fact that humans are conditioned to be negative. That's why positive music isn't all that popular. It's like when Kendrick dropped 'i', it had a great message and in my opinion, sounded great... but people said it was too poppy and corny. What's so corny about a song encouraging kids to love themselves? Lord knows there's a child right now who's dealing with self-hate issues. You could argue that the way it was done was corny, but... in a sea of toxins, if I see a potion, I'm gonna reach for it. Same thing when J. Cole had Crooked Smile on Born Sinner.
But as Kendrick himself said... Some of these kids take music VERY seriously. And as an artist, you have a certain level of power and influence over your fans. They gravitate to you for a reason. Music in itself is very hypnotizing, cause if it wasn't, we wouldn't place so much importance in it. Celebrities, especially musicians, are worshiped as gods to people. They get paid millions to go do what they do, and everyone sees it. That's why I can see where the OP is coming from. Artists DO influence. Now I'm not saying we shouldn't have fun music, because we do. There's a lane for everything. But I think instead of trying to eliminate the bad (Which is impossible, let's be real), we should bring in more positivity and try to make that the standard. And we also can't blame it solely on the music, because there's also many other factors that contribute to those problems as well. At the end of the day, people make their own decisions, so that's something we have to keep in mind.
