This is going to be hard to hear, but:

Bryan Adams released "Summer of '69" in 1985. A similar nostalgia-based song released now would be harkening back to the distant and bygone year of 2010.

@jsr This is going to be hard to hear, but:

Miley Cyrus released "Party in the U.S.A." in 2009, ten years after the first Britney song came on the radio. A similar nostalgia-based song released now would be harkening back to the distant and bygone year of 2016.

@yildo @jsr I mean people are talking like 2016 just happened, but brother, that was lifetimes ago.
