Start Battle Music Mr Mo's SBABS Lite

[davedani]

    I'm using Mr Mo's SBABS Lite and I was wondering if someone could create a small add on that basically starts Battle Music when the hero is near an event with a comment saying Start Battle. Also The Script would Start Boss Battle Music when the hero is near a boss. This would be Triggered by Start BBattle. To help create a battle mode feel, It would last detect if the "start Battle" Comment and "Start BBattle"  Comment are Erased, then it woulds switch to the Map's music.

If anyone could help me in any way, I'll be very greatful !!! I will credit anyone who helps.
