No 90s music because I think most of it could fit in really well right now. I'll give you a bit of room though. 1991 is alright.
Personally, I think Blisters in the Sun would be a really popular song if released now. It's really infectious and I think it would still be popular. It'd probably have a change of instruments though.
"In the Air Tonight" by Phil Collins has become very well-known, even though it's over 30 years old. It actually was re-released in New Zealand in 2008 and became a #1 hit there, after it had already been a top 10 hit 27 years earlier. Who's to say it couldn't happen on a global scale?
