Playlists and internet radio
----------------------------
forked-daapd supports M3U playlists. Just drop your playlist somewhere in
your library with an .m3u extension and it will pick it up.
forked-daapd supports M3U and PLS playlists. Just drop your playlist somewhere
in your library with an .m3u or .pls extension and it will pick it up.
If the m3u contains an http URL it will be added as an internet radio station,
and the URL will be probed for Shoutcast (ICY) metadata.
If the playlist contains an http URL it will be added as an internet radio
station, and the URL will be probed for Shoutcast (ICY) metadata.
forked-daapd does not support playlists in playlists (so for instance a .m3u
where one of the items is another .m3u or .pls).
Support for iTunes Music Library XML format is available as a compile-time
option. By default, metadata from our parsers is preferred over what's in
