That compact shuffle beat combined with the flowing piano progression in the verse are completely addicting to me.
But the guitars: The guitar work in this song is some of the best work ever put together. The compressed fuzz tone of the guitar is instantly recognizable. The imagination of the soloing throughout is a little added benefit of life on Earth.
The resplendent harmony everywhere is a monument to this great art: Vocal harmonies in the chorus, guitar harmonies in the instrumentals.
Major keys will be your release.
