[Redesign] Genre View loads extremely slow/long when a lot of tracks in it and displays artist text instead

[lukaslindnermusic]

using Online Mode.

I have quite some albums with the genre "Soundtrack".
When I am clicking on the genre, it says 0 Tracks 0 Albums and shows the following message (which appears to be intended for the artist view) for about 10-15s, until the view updates and the albums are shown:

Then, as soon as the albums get shown, it shows the (i guess correct) count of albums (in this case 597), but it shows 0 Tracks for quite some time until it updates (in this case to 13033).
I guess that it shows 0 until it is done counting in the background, and I understand that this might take some time in case of large amounts of albums/tracks.

Suggestion: For both the initial loading of the albums as well as the delayed calculation of the track count, indicate the loading. for the view itself, it could be a simple spinning wheel instead of the empty "artist view", and for the track count, instead of showing 0 Tracks let it say "Calculating..." or "Counting..." or something.

(I unfortunately still got no time to get familiar with Dart and the Finamp code, otherwise I would try to work on it myself.
Maybe in the next few months :P )

To improve the loading speed, couldn't it be possible to do it similar as with the albums list view, only loading the first x entries and then appending rows in the background?
