Why must you differentiate between one with tracks and one without? Can’t the software determine if tracks exist or not by the fact that they do not exist in the record? As a software designer myself I fail to understand why a song can’t easily have tracks added later to an existing “lyrics only” song if you decide later to do so….if I have a song with tracks where I have not yet added tracks but wish to add a duration I should be able to do so….and not have it assume that because there is not tracks currently that I don’t need a duration…….to have track types is mystifying to me as the flexibility is gone by doing so….just my .02….please allow durations to be added even when tracks are absent from a “tracked” song…..thank you
