What is wrong with my code please?

I'd like to compare songs by their length (measured in whole seconds). Add the required methods for ==, <, >, <=, and >= comparisons. Probably a good idea to be able to convert Songs to ints, too, huh?

songs.py 
class Song:
    def __init__(self, artist, title, length):
        self.artist = artist
        self.title = title
        self.length = length

    def __int__(self):
        return self.length

    def __eq__(self.length, other_song_length):
        return int(self.length) == other_song_length

    def __lt__(self.length, other_song_length):
        return int(self.length) < other_song_length

    def __gt__(self.length, other_song_length):
        return int(self.length) > other_song_length

    def __le__(self.length, other_song_length):
        return int(self.length) < other_song_length or int(self.length) == other_song_length

    def __ge__(self.length, other_song_length):
        return int(self.length) > other_song_length or int(self.length) == other_song_length

I have found this challenge to be very fickle. This worked for me, and it only worked for me when I copied it from someone else's answer in this forum. I typed this in verbatim and it didn't work, but when I copied and pasted the code, it worked. 

    def __int__(self):
        return self.length

    def __eq__(self, other):
        return int(self) == other

    def __lt__(self, other):
        return int(self) < other

    def __gt__(self, other):
        return int(self) > other

    def __le__(self, other):
        return int(self) < other or int(self) == other

    def __ge__(self, other):
        return int(self) > other or int(self) == other
