Description:
 def serialized(f):
 """Decorator that serializes access to all decorated functions. The decorator acquires pyspotify's single global lock while calling any wrapped function. It is used to serialize access to: - All calls to functions on :attr:`spotify.lib`. - All code blocks working on pointers returned from functions on :attr:`spotify.lib`. - All code blocks working on other internal data structures in pyspotify. Together this is what makes pyspotify safe to use from multiple threads and enables convenient features like the :class:`~spotify.EventLoop`. Internal function. """
