A clever but obscure detail about a song

My iPod screen reveals that in the song “Things Have Changed,” from the Wonder Boys soundtrack, Bob Dylan sings “The next sixty seconds could be like an eternity” exactly one minute before the end of the song. Never noticed that before.

Noticed anything like that in other songs? Lyrics, instruments, sound effects, tuning, tempo, etc.?

Okay, I’m revealing my age here, but…

When I first listened to Gordon Lightfoot’s Songs The Minstrel Sang through stereo headphones, I was delighted that after Gord sang “When the sheriff was there”, the phrase “they were over here” emerged from the opposite headphone.
