Again with the learning resource suggestions: Na'vi Earworms!

Rapid French by earworms mbt

The premise is that the repetition and the background music helps one memorise the words and sentences better. Also you learn pronunciation!

I don't have music skillz and my Na'vi is v much beginner level, but I could offer my voice to be the English-speaker, if someone would be interested in making this a project? It would need a script too obviously.

That's how I learned 食いつく:)
But even though Na'vi's lexicon isn't nearly as overwhelming as normal languages', ~1,700 words is still a lot to learn this way. At least revision will not be nearly as tedious.
So I guess it would be the choice between pleasant, and effective learning.

I doubt the point is to learn everything with this, but rather to get one to a start! ;P As someone whose brain is mostly controlled by the Instant Gratification Monkey I can appreciate easy learning tools. And I think Earworms are effective in that you will remember at least bits and pieces several years later, even if you haven't revisited it!
