Some game songs are fantastic songs in their own right. You actually want to listen to them when you're not playing the game. From what I remember when playing Taito's DS girl manner trainer My Happy Manner Book, there weren't any memorable songs that resonated. I'd be hard pressed to hum anything from that game! So it makes perfectly good sense that the game's soundtrack, including the theme song Happy Smiling, is on iTunes for ¥150 (US $1.25) a pop! Brian Ashcraft
