Script Request: BGM doesnt restart after combat

Very simple script (welli would think, i dont really know anything about  scripting *should probably start*
I would appreaciate any persons time to make this script for me, iwould think its a popular demand but.. i cant seem to find it .
But yeah, its sort of annoying to listen to the start of a BGM every 30 steps XD

Idk whether theres a script for this already, but if there is plz send me link or script, thx for reading. 

So, you want it to continue from the point it was at before the combat? Or do you just not want any BGM to play at all after the combat?

Oh hey, yeah the 1st one would be cool, resume it from before it got interrupted from battle music, plz
thx for reply!
