Playlists

Hello,

I need to set up a playlist, so I can control my Raspberry PI with XBMC with my Android phone (with XBMC remote app). My set up is:

Raspberry PI with XBMC
Windows PC with all the music and videos, shared to the Raspberry over LAN.
Raspberry mounts folders from Windows PC to /win/* (for example, music is /win/music/)

I tried creating a smart playlist from XBMC, I used filters with filepath contains "/win", and that's it. But yet XBMC doesn't find any files to the playlist? (Note that all files are properly found if I just go Music -> Files, but the playlist I just created is empty). I've tried many things, adding filters, pointing it to exact location (/win/music) and all, but nothing comes up in the playlists..

Any help? How can I easily set up a playlist, so I can for example select a song to play, controlling it all from XBMC remote application on my android phone?
