OK so it gives spaced repetition, but how? Does it just pop up the name of a song from a list you've entered, or is there more to it? There's not much information on what it actually does. Does it listen to your playing?

There is no listening to your playing at this point. That would be a cool feature, but I'm not ready to tackle that either.
