I saw this on Facebook the other night and it was immediately clear what this week's entry had to be: this astonishing cover, featuring a small army of great musicians, of the Beach Boys' "God Only Knows" -- which just happens to be my favorite Beach Boys song ever. (Yes, this might very well be by virtue of the song's perfect placement at the end of Love, Actually.)
Here it is. Amazing!
More info on this cover here. This thing made me incredibly happy.
