Splits to two panes if tablet in landscape
shows artists if request song is pressed on tablet - landscape
Uses a Master Pane to allow users to see the main fragment, the artist fragment, and the song fragment if they are on a tablet. Otherwise, they must open one at a time. Definitely going to be looking at making it look nicer soon
