Final Fantasy IV comes with nice soundtrack treat
Once you make Edward play your tune of choice, you can close up your DS, listen, and relax. If all of our DS games let us do this, we probably wouldn't have any need for our iPods anymore (okay, that's a lie).
It's important to note, however, that the soundtrack for the DS version is slightly different from that of the original game because of sound issues on the handheld. Regardless, we find this to be a nice little feature for the game.
