Code review comment for lp:~ahayzen/music-app/refactor-async-loader-pages

The reason this makes a difference is because we are now waiting to load the Songs tab until it becomes visible. I'm not sure the others really need to be loaded asynchronously--as they currently behave this way internally anyway.

I'd also like us to revisit what it means to load things in this fashion. There's a loading time hit for every CardView filled tab (and now ListView) we currently have in the app. So with this MP it's every tab. This makes it a bit annoying (slow and distracting, as well) to browse from tab to tab. I think a better idea might be to load things asynchronously, but do so upon app startup. Maybe wait until the current view has finished, then load the other views. This would mean the below Loaders would be made "active: true" and the CardView would be made to load when not visible. But we should discuss this.

Since this isn't very important for the goal of refactoring, let's think this through a bit more before making a decision.
