No, but it does change depending on where you go, and you get really used to it, I swear! Some of the places have really catchy tunes! Honestly, hearing a new song is almost half the fun of getting to a city you've never been to here.

This place is called Johto, and across the water, you have Kanto. Other than by boat, the only way to get from one region to the other is by the Magnet Train in Goldenrod. I hear Mt. Silver connects them, too, but I don't think anyone's allowed to go there for whatever reason. ...Which kinda makes me even more curious, to be honest.
