State of Chooser UI video

I watched the Chooser UI video where Craig implements most of the logic in the karaokemachine class. Unfortunately, I found the video very hard to follow. Some of the reasons are:

1. The video is somewhat complicated and everything is done in one go. Instead, it could have been broken down into two or three videos with quizzes/challenges in-between to test if the user understood what was done in the previous bit.
2. The methods seem somewhat mixed up. Every line in the method deals with either a new Set/List/Map object or an old Set/List/Map object. This might be too advanced for people who've just finished learning about collections in the first place. Again, it would have helped if instead of making 4 new methods (promptNewSong(), promptForIndex(), promptArtist(), promptSongForArtist()) at one go, a single video would have explained the logic for each method.
3. It's very obvious that the person writing this code already knows what methods are there in the class, so it's easy to implement a known logic (if you know the reason behind it). But for someone who's just starting out, it might not be so clear. For instance - what's the reason for each of those 4 methods. It would've helped if there was an explanation for these design decisions before writing the methods straightaway.

Anyway, these are just my two cents.
