The ninth track and fifth single on 1989 is about Swift hoping her lover will remember their best moments after they’re over. It expresses mixed feelings: hoping that they last, but knowing that they’ll end.

Surprisingly, the famous figure who gets the most elaborate attention is Lana Del Rey: Swift flat-out mimics her on “Wildest Dreams,” flitting between a fluttery soprano and deadpan alto, flipping lyrics so Lana — “His hands are in my hair, his clothes are in my room” — that it’s hard to tell if the song is homage or parody.

In the US, the song reached number five, becoming her fifth consecutive top ten from 1989.

According to Swift, the beats heard at the beginning of the song resemble her real heartbeats.
