You know how you can skip to the next song on a regular disk - you can't do that here with the download. I was given no outline of the material on the disk, so I have no idea what the reader is singing about. Either buy the disks (if you find a positive review of them) or avoid the thing altogether.
This is an excellent product. The songs are catchy, consise, and well organized. When used daily in studying Biblical Greek, they replace the memorization of dozens of other paradigms you need for learning the endings of Greek nouns, verbs, participles, etc. Theses songs greatly enhanced my learning and will be a tool I use for years to come.
My husband took four years of Greek. He commutes four hours a day and needs help staying awake while driving. I purchased this as a refresher...bad idea. He said it was awful. First negative purchase ever. Oh well it happens.the rating button doesn't work. I would rate it a -0.
