I just love that section of the song, you have the four notes in the harmonies further backed by the funky synth and the new jack swing beat, then you have synth lines weaving over the top between the chord changes. And then the strings rise up, which you can here well at 3:49 in the track, there is like 6 or 7 notes at once going on there, between the harmonies and the backing music, it's such a warm awesome sound, it frazzles my brain lol. I only hear such richness in classical symphonies or highly sophisticad jazz etc. Ive never heard it in other pop tracks, queen use it in bohemian rapsody, but they have live 5 notes going on in total for the intro, remember the time has like 7. His music was so much better written than all other pop, and the fact he wasn't musically trained shows it's really something from within, he's a genius
