Pasting a comment of mine from another thread:
Why can't "artists" sing about something more original than these hackneyed breakup and love-at-first-sight topics? They are so formulaic and bland. When you think about it, there is so much that people could sing about - our society is plagued by a plethora of issues, many of which are only going to get worse. Even if I disagree with the artist's take, I'd still have more respect for him if he could clearly articulate broader concerns through music. Better the wrong ideas, than no ideas at all.
I have also noticed that the music itself is a lot more homogenous than in previous eras. It is as if there are also harmonic and instrumental formulas to music if you want to be successful. For example: you can compare any piece of pop, rock or metal music and I guarantee that they are built on only four or five harmonies. The instrumentation is likewise becoming less interesting, I kind of notice an accepted sound and beat in each genre.
I have a few ideas about how this situation could be improved, but will leave that for a while. Let's get a discussion on the above going first.
