hm I wonder do we need the config option at all? can we just allow relative paths? joining on the basedir if the playlist line doesn't look absolute with no leading slash

the option mostly determines if the playlist is written with absolute or relative paths, I modified the reader so it does exactly what you described regardless of config option

If you'd like I can remove the config check during writes from the PR, but I think there's a lot of situations where absolute paths would still make sense (ie having playlists and music on separate volumes)

heya, just checking in. Let me know if you'd like this merged in!
