Collected books of lyrics are for the most part boring. What is the point of separating words from the music that carries them? When you have a lyricist of Lou Reed’s calibre, however, it is a different matter. Martin Scorsese’s intro praises Reed as someone who spoke for “the lowest of the low”, but it is the tender beauty that sticks, as on the Velvet Underground’s Pale Blue Eyes: “It was good what we did yesterday, and I’d do it once again. The fact that you are married only proves you’re my best friend.” You don’t get that from Ed Sheeran.
