Since my initial post I've picked up the following:
Big Bang Mini
Exit DS (GREAT game when you change the controls to D-pad/buttons only)
Korg DS-10 Synthesizer (not a game, but highly recommended to the musically creative)
Retro Game Challenge

It's a fully-functional synthesizer. You can make music and apply all sorts of audio filters to it. Like Mario Paint's music creator but much deeper. If you have a two-way audio jack you can hook it up to your computer and record it in high quality, too. Best $30 I've spent so far this year.
