Hard to top that one. That's probably the top pick for me too. However, it's a thread so I'll try to add a couple I think worth mentioning.
Everybody Wants to Rule the World
I Believe in the Beat
Let's Hear it for the Boy
These songs all instantly take me back to what I remember the 80s feeling like. It's a feeling like nothing I get from 90s or 2000s music. It's a careless happy that's hard to put into words. Some songs are timeless, these songs are not...and that's not a knock on them at all. They embody the 80s colorful, carefree vibes in a way that makes them perfect nostalgic time capsules. They don't grow old, but they're not timeless. They're quintessential 80s.
