What IYO, is the most perfectly crafted song ever written?

We have all offered up what our favorite songs are or greatest song ever written or played or sold the most records….but I want to challenge the collective to put more thought into their answer and offer up what you consider the best song ever crafted by a band. What I mean is the whole package. The lyrics, the melody, the opening lick and the ending, the musicians, the vocals, the beat, the pacing, the breaks, instruments used to get that special sound. It doesn’t have to be the most technical tune, just one you think that that band hit it out of the park with.

My vote would be for a lot of Beatles songs especially this one. Help me decide!

What say you??
