The song options screen contains information and editing controls for a single song.
Editing options are only available if the "Write enabled" options has been activated from the settings.
At the top you have song information including links to album and artist screens.
There are dropdown buttons to trigger playback of either the song, the whole album or this song and the rest of the album.
Editing controls include rating, options for adding the song to a playlist, and changing the song genre - optionally applying genre to the song's entire album.
