Hi,

i dont know, if i understand your question right,
do you mean levels = Subfolder?

Then there is no limit in levels.

The *.npl file looks like this:
FILE D:\Musik\Nightwish\Tales from the Elvenpath (2004)\04-nightwish- bless the child.mp3
FILE D:\Musik\Synasthasia\Synasthasia - Scotias Death.mp3
FILE D:\Musik\Nightwish\Tales from the Elvenpath (2004)\08-nightwish- stargazers.mp3
So, there is no problem with different sub-folder in a playlist.

It works perfect for me in NMC 07 ALPHA2a
