Whether it’s Feist counting cardinal numbers on the Anthropologie soundtrack or The Beatles getting melodramatic about old age, there’s something about math in songs. Namely: there’s not a lot of actual math. But there are a lot of numbers! Here are some of our favorites:

Ava Luna - Eight Nine Emily
Kate Bush - PI Peter
Feist - 1234 Kyle
2gether - U + Me = Us (Calculus) Dylan
The Beatles - When I’m Sixty-Four Scott

We’ll give you 50 gold for each song you can match up with the team member who chose it. (Our participants today are Kyle, Scott, Emily, Dylan, and Peter.) Send an email to contributor@slader.com.
