It's inside my head!

The Montreal Metro has an awesome and disappearing thing: the trains hum songs. I love moments of experience design built out of moments where the engine sound without this modulation would (in this case) create a humming that could drive a loaded rush hour train stark raving mad. On the other hand, depending on the song and how much of the song we get before the sequence loops, we might feel like there's a skipping record/cd, and madness ensues anyway.

Guess it is really a no-win situation.

I want to go to Montreal now to experience this for myself before these older trains disappear.
