What's up with the songs which have more recognition by later than contemporary generations?

    Wind of Change
    She Ain't Worth It
    Romantic
    Diamonds and Pearls

(only the first means anything to me, but this decade isn't really my 'zik)

I'd guess songs which get covered, parodied, or sampled are more likely to last?
