Well, there are a couple of things here.

(1.) There's a typo in your init.

In "songs = self.artist, self.lenth, self.title" you have "length" spelled wrong.

(2.) You're trying to cast "songs" into an integer, but "songs" isn't the type of thing that can be cast as an integer. int() takes a string and casts it to an integer, but "songs" is a tuple. You can either extract the relevant values out of the tuple or you can rewrite the class so it separates the variables that you need.

If you get stuck again, then let me know, and I'll try and help you.
