This question regards an recurring theme from lots of music I hear.
She had a ticket for the races just like me she was a victim of the night
- Tunnel of Love, Dire Straits
And I'm off to the races
- Off To The Races, Lana Del Rey
A Day at the Races
- Album by Queen
Many more examples exist, though I can't come up with a lot (I always notice them in passing).
Since it's so common, I'm certain there's some kind of metaphorical meaning to it - is there? What is it? What happens there?
