Stopping Music Mode causes a general error

I'm working on an app to flash a Yeelight RGB bulb to the beat of a song. From the API docs, it seems like I have to use music mode to get around the client quota of 60 requests per minute. I was having some issues getting it to work, so I wrote the following code to test what exactly was going wrong. Using a debugger, I found that telling the bulb to stop music mode causes a general error exception no matter the circumstances. I even tried creating a bulb object in a python console and got the same error. Am I misunderstanding how music mode works or is something else wrong?

Test Code

from yeelight import *
import time

inter = 2
bulbs = discover_bulbs()
bulb  = Bulb(bulbs[0]['ip'])



while True:
    bulb.stop_music()
    bulb.start_music()
    bulb.turn_on()
    time.sleep(inter)
    bulb.turn_off()
    time.sleep(inter)
    bulb.stop_music()
