mmh, I took the new version - but I'm sorry, I don't see (and hear) any difference to the status before. Perhaps we really talk here about different things in detail, I am not sure, whether your update and my "problem" have the same purpose.
Mostly I am using the Auto-DJ function - perhaps the Auto-DJ ignores the new feature.
Anyway, I ticked the tracks 1,2,3 from the the same album with the new flag, and whenever Auto-DJ takes one of those, only the chosen one is played. As mentioned in the posts before, I would expect, that always 1,2,3 are played as a associated sequence (beginning with track 1), whenever the Auto-DJ (or any other random playlist mode) choses track 1 OR track 2 OR track 3.
Perhaps you will find the time to look for that again - many thanks and a nice carnival weekend.
