 a Spotify client for that. You also can only listen to your music by letting
 forked-daapd do the playback - so that means you can't stream from forked-daapd

+LastFM
+------
+
+If forked-daapd was built with LastFM scrobbling enabled (see the INSTALL file)
+you can have it scrobble the music you listen to. To set up scrobbling you must
+create a text file with the file name ending ".lastfm". The file must have two
+lines: The first is your LastFM user name, and the second is your password. Move
+the file to your forked-daapd library. Forked-daapd will then log in and get a
+permanent session key.
+
+You should delete the .lastfm file immediately after completing the first login.
+For safety, forked-daapd will not store your LastFM username/password, only the
+session key. The session key does not expire.
+
+To stop scrobbling from forked-daapd, add an empty ".lastfm" file to your
+library.
