You don't think he remembers the numbers and colors? He might, he's just not saying it. When my kid first recited their 1-10 or ABC. They didn't recite a few. One day out of the blue they went from beginning to end. You might think they are not learning but they are soaking up and just might take some time before they start expressing their knowledge. That said, I would be annoyed to have that play on repeatedly.
