I already used up my credits for posting here years ago, lol... but I suppose new perspectives are worth something as well.
Music nowadays seems a bit of a cut and paste thing I feel. With all the songs using samples from classic songs, some genres doing it more than others and some acts actually doing covers, and still end up in the charts, it makes me wonder how much we actually want something new.
I had no clue what was in the charts (and with that I'm only addressing pop music) but I decided to look it up and it's the same formulaic stuff that has been around for decades, just with better production values every single year. I suppose you can't really argue with that kind of approach in that it works to sell songs and provide earwurms to most people; and thus the purpose of pop music is complete.
However; I feel that if I look into other genres; and I really don't get into every genre (country/country rock for example doesn't do a thing for me), but for the ones I do enjoy (a lot of metal/rock, goth, most electronic dance music styles and some rap) I do see trends both in style and in terms of production (and the entire technical aspect), where EDM in general seems to hold a high ground in both style and production since it sprouts different styles regularly often because of said production (dubstep, even if it's already around for almost a decade, being a good example, since it's a result of automated synthesizerprogramming that's possible because of all the digital production software; hardly a realistic thing to get into when it was all analogues; but there are some other contemporary EDM subgenres that revolve around specific techniques).
Content in terms of lyrics in music nowadays; I suppose it depends on the genres you're into. I never got into pop music, so the, to me, superficial topics and dozens of lovesongs kinda go past me. Other genres; depending on subgenres I feel are a bit more timeless in that there are plenty of metal songs about death and decay and have been around in the 90's as well. Rap still has a thuggish image ever since it was a thing, goth kids still mope around, lol... and electronic styles; they often don't even feature lyrical content...
Yeah, that's a random 2 cents I had to spare on the topic right now
