I actually didn't know what that was so I got the GoF book and looked
it up. It appears that it already is the strategy pattern, with the
(sort of) exception that the object asking it to perform is strategy
is the EngineObservor and not the class with the data to be
manipulated (the PlaylistModel).

I agree with you here. I'll break up RandomMode if it turns into a
bunch of confusing if's.

Regardless I want to have a StandardMode just to have something to
start off with.
