How to estimate it

Fermi’s official “Napkin math”

The Beatles released 12 studio albums. Call it about 16 songs each, so roughly 200 songs total. How long is each one? Short by today's standards, maybe 3 minutes.

Minutes each

200 × 3
≈ 600 min, about 10 hours

Rounded assumptions may give a slightly different estimate. The official answer above is the game’s reference value.
