I started off just making a simple UI to browse artists and albums. With relatively little code I was able to create the basic artist/album tabs with list views displaying the contents. 90% of the players I looked at use this type of layout to browse your collection so I am using that as a starting point.
The contents of the lists are hardcoded. So my next step is to feed those into a data source.
Now to hit the gym and get dinner before I settle down into a long night of coding.
