Why create sub model Playlist of model MusicLibrary?

I fail to see the importance of creating a sub model Playlist for our main model MusicLibrary. Why don't we just add the methods we want into our MusicLibrary.m in order to fetch a specific index of the Library array instead of creating a new model which will have a custom initialised method for that? Isn't that extra step a bit unecessary?

A play list would only include portions of the MusicLibrary. This feature would call for a new method. Also...title, artist, album, genre, etc are different attributes which would call for more programming. Adding these extra steps make the MusicLibrary more user friendly.
