Maybe I have overestimated the number of tracks that were used in demos... A quick check at BitFellas:BitJam shows that at least 6 tracks were used in regular demos, and some others in music disks or disk magazines.
To play or not to play shouldn't make a difference for the definition of soundtrack, I would think. Especially since soundtrack is normally applied to movies too.
Re-reading the help text on the submission form, I think that actually both "Original Work" and "Original Soundtrack" should be selected, since there is at least one track of either kind.
Anyway, I can also live with "Original Work" as release type. I just thought my edit was kind of obvious, but it turns out it isn't.
