When I use music for the main menu in Tiny Tanks it won't work!!!

I typed it properly in the interface.xml file.
What's going on?
Did you put the music in te music folder?
Don't forget, '.wav' only!
does dim3 buffer or does it load the complete track in whole?
I'm guessing complete track. Last time I loaded a 13mb music file it froze for a second.
hmm okay and how is the looping?
It's a .wav and it's in the music folder.
Bitrate? Channels? Should be 44khz stereo if it's background music and mono if it is a sound effect. Also the music has to be turned on in the settings and it should be 8 or 16 bit sound.
I get that 2 but not with munu music---
case 1: "Rain" as a background sound (lol rhyme)
case 2: "weaponfire1" as a gun sound (LOL its from utb but since it not work im not using it)
I keep solving my own problems. My interface.xml file was messed up so I'm using a different one. Now it works, it sounds GREAT!
