Sometimes, you can hear a song 1,000 times and only remember the chorus. Blame the brain and its wiring or the vagaries of the human attention span — but often, the bulk of a song can just slip on by. “I Want You” falls into that category. It begins on a sour note: “The guilty undertaker sighs/ The lonesome organ grinder cries.” But almost immediately everything drops away because the music is just so damn sweet. That light, bouncy guitar hook that pairs up with the piano at the end of every forth verse for the descending hook — it might be one of the few truly euphoric moments in a Bob Dylan song. And of course, there’s the repetitively longing chorus. “I want you, I want you, yes I want you, so bad/ Honey, I want you.” Who doesn’t want someone to feel that way about them? The last song recorded for Dylan’s monumental Blonde on Blonde, the first true rock double album, “I Want You” has been described by BBC Radio’s Jeremy Vine as having a “melody wrapped in tinsel … all bouncy and joyous.” He’s right. Give it another listen. You’ll quickly find yourself all bouncy and joyous.
