Solution 1:

filetypes=(("Mp3 Files", "*.mp3")) is equivalent to filetypes=("Mp3 Files", "*.mp3"). I'm guessing you intended for the outer parentheses pair to be a tuple, but that requires a trailing comma. Or you can just use a list.

self.fname = askopenfilename(filetypes=(("Mp3 Files", "*.mp3"),))

Or

self.fname = askopenfilename(filetypes=[("Mp3 Files", "*.mp3")])
