Estoy tratando de recorrer las canciones cuando hayas terminado con la siguiente sin repetir una canción. ¡Muchísimas gracias por su ayuda y apoyo!

Sólo usaría el random.shuffle método de la random Biblioteca, en lugar de ajustar la lógica usted mismo para asegurarse de evitar duplicados.

import random
music = ["So_Far.mp3", "Love_Game.mp3", "Asshole.mp3", "Baby.mp3", "Bad_Guy.mp3","Beautiful_Pain.mp3", "Berzerk.mp3", "Brainless.mp3", "Desperation.mp3",   "Evil_Twin.mp3", "Ground_Hog_Day.mp3", "Legacy.mp3", "Rap_God.mp3", "Rhyme_Or_Reason.mp3", "So_Much_Better.mp3"]

Puedes usar random.shuffle aleatorizar el orden de la lista

random.shuffle(music)

Ver ... al azar

>>> music
["Legacy.mp3", "Love_Game.mp3", "Beautiful_Pain.mp3", "Asshole.mp3", "So_Far.mp3", "Evil_Twin.mp3", "Brainless.mp3", "So_Much_Better.mp3", "Rhyme_Or_Reason.mp3", "Bad_Guy.mp3", "Baby.mp3", "Desperation.mp3", "Berzerk.mp3", "Ground_Hog_Day.mp3", "Rap_God.mp3"]

Ahora solo recorre la lista aleatoria y reproduce tu música.

for song in music:
os.startfile(song)
