Hide the years that ncpmpcpp always adds to the library albums, and
don't split them by date. Also importantly use 'album_artist' to
sort the corresponding artists instead of just 'artist' since beets
will often sort the individual acting artist for the latter, pulling
apart single songs from larger albums.
Lastly, add a 'data_fetching_delay' (of I believe 250ms) when quickly
scrolling through the artist/album list so it goes a little smoother
when loading data from remote sources.
