"Like Rock & Roll and Radio" by Ray LaMontagne
This is such a powerful song, that I almost don't want to talk about my emotional reaction to it--maybe you should listen first:
Are you still in love with me
Like the way you used to be
Or is it changing?
And in the second verse, listen to the delivery of the last line:
...has the weight of all the years left you hollow?
By the time he gets to the chorus, you could crush me with a feather.
I generally try to avoid sad songs, because while they can be cathartic, they can also be quicksand. But this song is so compelling, I just have to marvel at it. It's like looking over a cliff. Beautiful and terrifying.
