Synology M3U Playlists

[simoncn]

You can use relative playlists on any device (Synology, Sonic Transporter, Windows PC, etc.) This is the recommended approach because relative playlists are portable from one device to another without needing to be edited.

With your library structure, I suggest putting the 'playlists' folder for Synology in the the same place as you have done for Sonic Transporter (a subfolder of the 'music' folder). Your .m3u playlist files would contain paths such as:

../[Genre]/[Artist]/...etc

These playlist files could be used on Synology or on any other device with the same folder structure.
