Radica Play TV game - OPUS (2000)

I got this game back when it first came out, and I still love it! It is a simple enough concept that a child can play it, yet complex enough that it is still interesting to an adult. There are 16 different songs, all a pleasure to listen to, 3 different difficulty levels to play, and a challenge "red ball" mode. Definitely one of my favorite "plug and play" games.
