downloads: base album/artist progress on completed tracks

Browse Source 
The aggregate summed bytes over only the currently active songs, so it
reset each time a track finished and the next one started. Count completed
tracks (plus the fraction of each running track) over the node's full track
count instead, so it climbs one track at a time.
