That's strange? those code should work, but I´ll check them out again.
And yes, this game is yet full of flaws:P But talking about the music, I didn't chose to use the rpgmaker games(coz they're kinda used a lot), but in my future projects(hopefully) I'll design music myself to make it more vivid as you're talking about, and dialogues as well:P
And thank you for your time and advices :D Wish you had a good time
