KeyboardInterrupt

Steps/conditions to reproduce the bug

If I run audio_metadata.load(Path(df.loc[3421]['FileA'])) Or this file is accessed during my dataframe.appy() loop, then the process freezes.
If I wrap this call in a function eg..

import time
import timeout_decorator
@timeout_decorator.timeout(1)
def mp3meta(path):
    audio_metadata.load(path)


mp3meta(Path(poo.srcdest[0], poo.df.loc[3421]['FileA']))
Traceback (most recent call last):

  File "/tmp/ipykernel_384411/3184206738.py", line 1, in <cell line: 1>
    mp3meta(Path(poo.srcdest[0], poo.df.loc[3421]['FileA']))

  File "/home/me/.local/lib/python3.8/site-packages/timeout_decorator/timeout_decorator.py", line 82, in new_function
    return function(*args, **kwargs)

  File "/tmp/ipykernel_384411/2936242082.py", line 3, in mp3meta
    audio_metadata.load(path)

  File "/home/me/.local/lib/python3.8/site-packages/audio_metadata/api.py", line 113, in load
    parser_cls = determine_format(data)

  File "/home/me/.local/lib/python3.8/site-packages/audio_metadata/api.py", line 72, in determine_format
    ID3v2.parse(data)

    return wrapped(*args, **kwargs)

    self.tags = ID3v2Frames.parse(

  File "/home/me/.local/lib/python3.8/site-packages/audio_metadata/utils.py", line 57, in remove_unsynchronization
    if data[sync_index + 1 : sync_index + 3] == b'\x00\x00':

  File "/home/me/.local/lib/python3.8/site-packages/timeout_decorator/timeout_decorator.py", line 69, in handler
    _raise_exception(timeout_exception, exception_message)

  File "/home/me/.local/lib/python3.8/site-packages/timeout_decorator/timeout_decorator.py", line 45, in _raise_exception
    raise exception()

TimeoutError: 'Timed Out'

So it seems that somewhere inside 'remove_unsynchronization' there is the capability to create an endless 'while' loop. I don't know what is special about this file. It plays ok as does the previous file (ie the track before).
