Music Playlists

Hi all, I would like to create some playlists for my music. On my laptop I use Foobar, on my phone I use Samsung Music.

My music sits on my NAS, and syncs down to both my laptop and phone.

The issue I have with playlists, is that the directory changes. The playlist directory on my laptop would begin with, for example C:/users/Media and my phone /Internal Storage/Media

Does anyone know if there is a directory format that works from the folder of the playlist, and not the root directory of each device? For example once we get to Media/My Music/... This is the same on every device.

Any help, ideas or suggestions welcome. Thanks.
