My experience has been that, as soon as I upgrade my BIAB each year, I notice some of the "new" RealTracks in the latest release are already marked as favorites in the stylepicker! This confused me at first until I looked closer and discovered that the 49-pak I purchased the previous year has now become a part of the new release! Seems a bit shady to me since they do not disclose this. But I still buy the latest 49-pak because that way I get it this year instead of waiting for it to be repackaged into next year's release.
