Yes, could be. I actually *bought* a bunch of these - at one time, I could buy them at our local sheet- music store; they had a Tune1000 computer in the store, I think you took away a floppy (!) with whatever songs you bought. I remember it seemed like a legit, Tune1000-company thing, versus the music store selling "bootlegs" ...
