"Helicopter", by M. Ward.
She doesn't know this, but when Ms Sarah Knuckey made a copy for me of M Ward's "Transfiguration of Vincent" LP, way back in twenty-zero-whatever, she changed my life. (And now I have my own copy. Ten bucks at the local second-hand music shop.) At that time, I didn't know music like this was still being made. Alongside Iron & Wine and Gillian Welch, M. Ward's music gave me renewed faith in the, uh, redemptive power of music. Or some such.
So, Sarah, if you are out there, this is for you.
Editor's note: it is entirely coincidental that the last two "songs of the day" have been about helicopters. This is not a trend.
