What I would like is the following:
Select 1 song , start playing, and have Amarok automatically append songs to the playlist based on the \'suggested songs\' from audioscrobbler.

scenario:
Song A plays, Amarok retrieves suggestions for songs, picks one and appends song B to the playlist, Song B plays, Amarok retrieves suggestions for songs based on song B, appends song C to playlist...
repeat while(true);

Alternatively: create a smart playlist where the user selects a song and a requested number of tracks in the playlist, Amarok creates a playlist based on mechanism described above.
