Singing on the Metro

I see people all the time on the Metro with little white earphones plugged into their heads, and I wonder constantly why more of them don't just burst into song (or at least nod their heads to the beat). No; it's mostly that dull, Monday-morning commute-stare. Not that I don't understand the dull, Monday-morning commute-stare, but this morning Sigur Ros popped up on my iPod (free mp3 here), the sun was shining, the air was crisp and shiny and suddenly it was quite a bit like being in my very own Sofia Coppola movie -- a little trippy, a little spacey, a little bit of public transportation -- but definitely worth breaking into song for. La la la.
