Music Player in Primo? How to set folder to scan

I'm trying to use the Music Player and Primo and would like to know how to set it to look in a specific folder on my SD card for music.
Right now it is scanning all the system sounds from Primo and they are showing up on the list. I would like to exclude the system folder and set just one folder to scan for my music.
I'm guessing this is something I have to set in the Sys.txt but don't have a clue how?

Put this in your sys.txt:

[oasis]
exclude_directories="%myflashdisk%\,%root%\windows,%sdcard%"
include_directories="%sdcard%\Music,%sdcard%\DCIM"

You can replace the music folder and/or the DCIM folder with your own choice. Personally, I use those folder for music and pictures.
