When I display my top albums chart, I'd like to have the possibility to mark an album as a soundtrack. Thus to choose if the chart should list soundtracks too, only soundtracks or no soundtracks at all; just like you can choose to show 4 or 8 albums, from the last 7 days or overall. This because I usually count OSTs as a completely different type of scrobbling compared to canonical albums. Basically, I'd like both to see and count how many soundtracks I scrobbled from my library with a single clic, and to see my grid with regular LPs without soundtracks.
This also blends with the possibility to count scrobblings from an album with different artists as a single entry (i.e. not only split albums but also soundtracks with selected tracks from various artists).
An alternative could be the possibility to generically mark albums with a special tag (i.e. I could name it "soundtracks" or "Kazakhstan albums" or whatever) and have in the dropout menu a check for user personalized album marks, so that the chart could show them or not and everybody could personalize that.
