* Song lists for artist, album, and overall now shows the artist name for each individual song
* Added display artist column to songs table. This required a DB upgrade and users should
do a refresh for music items to be able to see the display artist in the song lists.
The SongsListFragment lists all available songs for a connected host or
for a specific artist.
Added the songs tab to the music screen and to the artist details
screen.
When user selects artist from ArtistListFragment it will now
show a screen displaying artist details. I've taken the TV show
details setup as an example.
This adds the following new functionality:
* Displaying artist fanart
* Displaying artist description
* Download all songs from an artist
