And most books have drama and protagonists and antagonists.
Art and music and literature almost always comes from conflict – it is the interaction between people (often corrosive) that provokes emotional responses – and that gives the singer or author or poet something to write about.
There is nothing new in your observation. Conflict is what makes the world go around.
Since this question has been placed (badly) in ‘General’ I can’t do more than answer the OP’s ‘serious’ question: Yes, I have noticed, but I don’t suppose it’s that odd.
Oh, I guess I can place the odd remark or two, but I’m sure it’ll all be modded off.
Average people without a zeal for music tend to like unoffensive and stale themes like love and relationships and shit. There is no exploration into anything that would make them feel and especially appear abnormal. If it’s on the radio it must be good right? Some 20 year old teeny bopper with a canned sound track and auto tuned vocals sells just like shitty, burnt, overpriced Starbucks coffee. People who buy into that can’t be bothered to understand thisthisthis or this, hope I’m not being to harsh.
