Show off my DS4's interest in music!!

Since we got him piano, he is so into it, always wants to play. He can sit there hours to read his piano book and watch the DVD, and self taught himself quite many simple songs.
He was in group music class with ten similar age kids, but he is away ahead of them, maybe because he pay so much attention on it, and practices it hours everyday, his log tern spam is amazing!!

My colleage said he is very jealous because his DS not very much into music:-)
