These days?? As if it just became popular music (bustin your chops)...I cant speak for everyone but I was born in 85. I grew up on electronic pop music. My mom used to kick the old jams like Rhythm Is A Dancer lol. First CD I ever owned was Ace Of Base - The Sign and I played the shit out of it. So this isn't a "new thing" for me.
Even as late as these aqua songs came out, they were still massively popular and now when you compare it to newer music (on top of actually being able to judge music/production), you gain a better appreciation for songs from this era.
I know there's no hate intended. I personally don't think it's about being open minded. You just dig what you dig, cant help that.
