The error above appear but only with MP3 Files and not when I open a python File instead
 from pygame import mixer 
 mixer.init() 
 mp3button = Button(master, text="Choose MP3", highlightthickness=0,bd=0, bg='black
',activebackground="black",fg="white",  command = lambda : see_check())
  checkvar = IntVar()
    checkplay = Checkbutton(master, text="Play MP3?",variable=checkvar ,onvalue=1 ,offvalue=0 ,font=('Arial',12), bg='blue', fg='white', activebackground='blue', activeforeground='white')
  def see_check(): 
        if checkvar.get() == 1: 
           
                file = askopenfile(mode='r',filetypes= [('MP3 Files', '*.mp3')])
                if file is not None: 
                    content = file.read()
                    mixer.music.load(content)
                    mixer.music.play()
How I get rid of this ? Thanks in advance :)
EDIT : Not working with mixer the sound does not play
EDIT 2 : It just display x00\x00\x00\x00\x00\x00\x00\x00$\x05\xc0\x00\x00\x00\x00\x00\x00\x11\x83B\xb6\x10\xe0\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\xff\xfb\x10D\x00\x0f\xf0\x00\x00i\x00\x00\x00\x08\x00\x00\x0f\xf0\x00\x00\x01\x00\x00\x01\xfe\x00\x00\x00 \x00\x00?\xc0\x00\x00\x04\xff\xff\xfa\x98\x95\xa8\x9f\xff\xfc\xeb\x1cD\xfcn<\x18t\x and more even if I want to play the content not printing it
