This is an old topic...
Anyway. I think I wrote a whole rant on this once, oops. It's not that current music sucks. For one, you gotta seek out what you consider to be the "good" music - just as you probably would have had to back then. You can't just base your opinion on what's on the charts because there is modern music beyond that.
Plus I always see people saying "oh, these songs nowadays, all about sex drugs, blah blah..." but when listening to music from older times like the 80s in my personal opinion I'm still seeing as much of that kinda stuff in the songs anyway, maybe the meaning might be more hidden in some songs but it's there. And why does that automatically make a song bad?
We have enough intelligence to decide what we should take as gospel and what we shouldn't, so songs don't always have to have meaning, we can just enjoy them (although it does get problematic when it starts encouraging really bad things. but we need to learn that hey, we don't have to take this word for word, it can just be a stupid little guilty pleasure song like "oh you listen to that idiot Bob Crackers?" (Idk I made it up) "well, yeah man, his lyrics are terrible but the beat is good.") Idk.
Also what's already been said above. You remember the good music of those times bc it made an influence on you, not what you might consider bad music bc why would you want to do that unless it's a joke like that fox song. And in some people's cases it was part of their youth which people tend to treasure so they might miss the meaning in old songs anyway and come back to it and listen and be like "oh my god this whole thing is a big innuendo, how did I not see that" or they make a really big thing out of that music bc it reminds them their youth which a lot of people are like "ooh, yeah those were the days."
P.s I'm not calling you old. Or saying that you have bad music taste. Quite the opposite, music is the same as always, you just gotta mine for the music you like.
