My time has come. As someone who almost exclusively listens to instrumental soundtrack from movies and games, including from games I have never played, these are the ones that most often get stuck in my head (in no particular order). A plus "+" indicates a song that got stuck in my head regularly before I ever played the game, while an asterisk "" indicates a song that still gets stuck in my head, despite being from a game I have never played at all.

Ω) Town Theme - Final Fantasy II
