Pygame doesn't play mp3 files tagged with mutagen

Question

After tagging an audio file with mutagen pygame no longer seems to be able to play the file. It however loads the file successfully and the call to pygame.mixer.music.play() throws no error. I actually use the music-tag library which is just a wrapper around mutagen for tagging the files. Was wondering if this is known issue.

Code for tagging

import music_tag

f = music_tag.load_file('sample.mp3')
f['title'] = 'Smells like teen spirit'
f['artwork'] = open('nirvana.jpg', 'rb').read()
f.save()

Code for playback

from pygame import mixer
mixer.init()

mixer.music.load('sample.mp3') 

mixer.music.set_volume(0.7) 
mixer.music.play(-1) 

while True:
    query = input()
    if query == 'q':
        mixer.music.stop()
        break;

I've also noticed that on removal of the tags, pygame does play the file except the playback is really, really distorted and very different from the actual audio on the file. Meanwhile other mp3 players play the same file with or without tags just fine.

Answer 1

input () blocks the entire application until an input is made. Use the KEYDOWN event to detect when q is pressed (see also Problem when using keyboard commands in pygame):

from pygame import mixer
mixer.init()

mixer.music.load('sample.mp3') 
mixer.music.set_volume(0.7) 
mixer.music.play(-1) 

run = True
while run:

    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            run = False

        if event.type == pygame.KEYDOWN:
            if event.key == pygame.K_q:
                mixer.music.stop()
                run = False
