External Playlists not loading

I’m creating playlists from an external source. Files are on a NAS, locally mounted and accessible yet I cannot load the playlist (playlist window remains empty)

This is my playlist file: 90.m3u

#EXTINF:0,The Verve - Bitter Sweet Symphony
/mnt/NAS/music/mp3/The Verve/Urban Hymns/01 Bitter Sweet Symphony.mp3

File is accessible:

file "/mnt/NAS/music/mp3/The Verve/Urban Hymns/01 Bitter Sweet Symphony.mp3"
/mnt/NAS/music/mp3/The Verve/Urban Hymns/01 Bitter Sweet Symphony.mp3: Audio file with ID3 version 2.3.0, contains: MPEG ADTS, layer III, v1, 128 kbps, 44.1 kHz, JntStereo

Also, tried via command line:

volumio@volumio:/var/lib/mpd/playlists$ mpc clear
volume:100%   repeat: off   random: off   single: off   consume: off
volumio@volumio:/var/lib/mpd/playlists$ mpc load 90
loading: 90
volumio@volumio:/var/lib/mpd/playlists$ mpc play
volume:100%   repeat: off   random: off   single: off   consume: off

Permissions on folders:

drwxr-xr-x 5 mpd audio 4096 Apr 21 2014 . drwxr-xr-x 41 root root 4096 Oct 8 2014 .. drwxr-xr-x 3 mpd audio 4096 May 16 2013 .cache drwxrwxrwx 3 root root 4096 Apr 21 2014 music drwxrwxrwx 2 mpd audio 4096 Jun 9 10:00 playlists -rwxrwxrwx 1 mpd audio 181 Jun 9 10:29 state -rwxrwxrwx 1 mpd audio 3072 May 16 2013 sticker.sql -rwxrwxrwx 1 mpd audio 3864 Jun 9 10:03 tag_cache

Only thing I could think of, is that I guess mpd will only play files relative to its defined music directory, ie:

music_directory “/var/lib/mpd/music”

Is there any way around this, by using an absolute path?

I guess I can create a symbolic link in /var/lib/mpd/music if that’s the case…

Please help.
