a lot of contemporary popular music is not very good, and this has been true of every era in the past. the good stuff is what people remember and still listen to decades later, so maybe you've been waiting for the cream to rise to the top. it takes a more concerted effort to filter through the noise yourself
also there can be an overexposure problem with new music, I hate when a song becomes so popular that you can't escape it and it loses its impact. I recently heard "Somebody That I Used to Know" for the first time in years and realized it's a genuinely great song but I didn't appreciate it at the time because it was fucking everywhere
though these days the very concept of "popular music" is dying along with the rest of the western monoculture so idk what if anything from the modern era will stand the test of time. the mainstream can be more easily ignored than ever before. there's so much great music out there though, you just have to find the right niche(s) that appeal to you
