Because the strongest examples capture something specific about their era's actual production techniques, cultural anxieties, or technological novelty, rather than just being catchy within a genre that could plausibly exist in any decade, giving them a distinctive sonic and cultural fingerprint tied to a specific moment.

If you want a song that captures the 1980s
"Take On Me," a-ha. Its synth-driven production is genuinely inseparable from 1980s new wave's specific sonic identity.

"Uptown Funk," Mark Ronson featuring Bruno Mars. Captures a specific mid-2010s revival of retro funk and soul influences within mainstream pop.
My honest opinion on why "Smells Like Teen Spirit" so thoroughly defines the 1990s in a way few other songs manage for their own decade
I think it's because the song didn't just reflect an existing trend, it genuinely helped cause a real, immediate shift in mainstream music's dominant sound and attitude, giving it a causal relationship to its decade's identity rather than simply being a popular example within an already-established trend.
Does a song need to have been the biggest hit of its era to genuinely define that decade?
Not necessarily, some genuinely decade-defining songs weren't the single biggest chart hit of their specific year, but achieved a broader, more lasting cultural and sonic significance that outlasted songs which charted even higher at the time.
