I transcribed this song for a student as it was an excuse for me to learn this great song. It's a solid example of intricacy, solid melody, and arrangement.
The secret to learning this song and others is to get the bass line happening. I transcribed this song so that the bass line has the stems pointing downwards. The rhythm and melody notes have the stems pointing upwards.
Like I said, get the bass line happening, and then work in one rhythm or melody note at a time.
Also, try and sing it to your self. Give your self an idea of what it should sound like.
