I've tried the first exercise. What I think would help me is when I get an answer wrong and get, e.g., Nope, "Major 3rd" is not correct, provide a button to play what the Major 3rd would actually sound like so I can compare it with the question and memorize.

This looks like exactly what I've been looking for, though, I think I'll try getting into learning with it.

Good idea! There's an advanced option that puts a "listen" button next to each interval on the sidebar in the intervals exercise, but this would be a good more general feature to include for whenever someone answers incorrectly in any exercise.
