not sure if this is what you mean but running this batch lets you select which ini file to use. All you have to do is save your jukebox.ini as a different filename but in the index section specify a different songpath. (You can also have different skins, credits anything)
Edit the batch file where i have "newskin" to whatever name you use.
copy and paste into a new file e.g. wincab.bat
@echo off
: :: the directory where wincab lives
cd\juke
: :: change the on screen message to whatever you like e.g. playlist1, playlist2
echo For cd skin press 1
echo For newskin press 2
set/p ini=[pick skin]
if %ini%==1 goto cd
if %ini%==2 goto new
:cd
wincab jukebox.ini
goto end
:new
wincab newskin.ini
goto end
:end
